In the computer room of the School of Microelectronics of Huating Jiaotong University, Xin Kaiyuan looked at a hot post that appeared in the forum on the screen, and after a 'I top', he picked up a pack of cigarettes on the table and got up to scatter it for his brothers.

But what surprised him was that at this time, as if it was the same, there were many people standing up in the computer room, and they seemed to be emitting smoke.

"Lao Xin, come to one!"

Funny took the Ashima handed over by Luo Kaishun, Xin Kaiyuan and a few friends walked to the door of the computer room.

emmm……

There are many more people who go out.

Then they looked at each other, and a knowing smile appeared on their faces.

Cheng Jin took the book and looked at it, and shook his head helplessly, "Domestic textbooks...... Alas......"

If the sky is over, let him be the general manager and be responsible for the operation, but another group of managers of state-owned enterprises, especially the financial director, must be dispatched by state-owned enterprises, and his tricks cannot be concealed in the end.

Until nightfall, Cheng Jin sat in his position, and the ashtray on the table was full of cigarette butts.

He thought about it, first deal with it coldly for a few days, wait for ten days and half a month, and then talk to Qingyun about it when the limelight of public opinion has passed.

Besides, with money and people, it is not impossible to carry out a real reverse restoration project.

Among them, he invested 450,000 yuan, Huating Zizhu Venture Capital Co., Ltd., a local shareholding platform, invested 643,000 yuan, and Huating Zichen Information Technology Co., Ltd., a shareholding platform of Huating Jiaotong University, invested 2.55 million yuan.

So at that time, he wanted to find that cheap student, hoping to dispel his thoughts.

Compared with himself, Cheng Jin felt that his son was even more of a genius, only four years old, and he could solve the one-dimensional quadratic equation well.

However, he still did not twitch, and kept kneading the eyebrow area between his right thumb and forefinger.

But......

Therefore, at the shareholders' meeting, his opinion is not important at all.

Big trouble.

At this moment, Cheng Jin panicked.

"Teacher, what is a stochastic process and why should it be introduced?"

I don't think about anything, and I have all the thoughts pouring into my head.

You can think of it as either a random process as a set of all sample functions, or as a random process as a set of random variables at different moments in the course of time.

Qingyun is certainly talented, but Qingyun has only been in the cold for ten years, and he lacks accumulation.

Cheng Jin spoke carefully, and Qingyun recorded quickly.

Numbness.

While speaking, Cheng Jin flipped through the textbooks brought by Qingyun, judging from the creases of the book, this kid's progress was indeed very fast.

If there is no order, there will be no economic benefits, and I have every reason to propose not to support idlers and postpone the dispatch of state-owned assets.

What is too calorific, what is unstable, just make it up.

The decoration company he found, only one master in the entire company can have this technology.

"Give me a pack, I just don't have it."

But when he walked out of the Yanhuang Group, he suddenly reacted.

After extinguishing the cigarette, Cheng Jin packed his briefcase and rushed home.

Qingyun's operation was not at all what he had imagined before, it was a discussion and discussion between academics and academics, but he directly smashed the order.

As long as Qingyun is dealt with and he is asked to cancel the order, then the crisis will be solved by itself.

Cheng Jin smiled.

According to Qingyun's learning progress, Cheng Jin asked a few basic knowledge one after another, and when he saw that he answered fluently, he was also quite satisfied.

"That ID is called 'Qing Yun Light Breeze', and Xiao Qing's several vests are very recognizable."

Since the source, noise, and signal transmission characteristics of communication are all randomly changing, they can be described as random processes.

“emmm…… You say, is it that when Xiaoqing is always with a girlfriend, he uses the corresponding IDs, and when he is alone, he will use 'light and light'. ”

This student is different from other students, learning is only a small part of his life, but he has such a firm grasp of the basic concepts, which shows that he really took the time to put in a lot of effort.

Cheng Jin smiled when he heard this, "Because most of the signals and noises encountered in communication systems can be regarded as smooth random processes, it is of practical significance for you undergraduates to study smooth random processes. ”

When Qingyun heard this, he was not polite, opened the textbook he brought, pointed to a passage and asked,

At the Yanhuang press conference, Cheng Jin really panicked, where did he have so many chips to deliver?

Rubbing the chip by hand tests the craftsmanship of the mason master.

After all, it's a cat and a tiger, and in the past few years, I've actually almost mastered the technology.

"Semiconductor materials have good frequency characteristics, small size, and low power consumption, which is convenient for the integration of circuits, and the products are also particularly outstanding in terms of robustness, seismic resistance, and reliability.

How to physically operate Hanxin Company, change the pilot test to production, and quickly increase production capacity, so as to smoothly undertake the order of 1 million DSP chips sent by Yanhuang Group.

"If it's a company-related thing, Xiaoqing's general ID is 'Qing Yun Yao Yanhuang'.

When he sat in the conference room, Cheng Jin realized that he was really going to be finished this time.

"Sources, transmitting devices, channels, noise sources, receiving devices, hosts.

There is only one theme for this conference.

"Teacher, why do we generally study generalized stationary stochastic processes?"

The corners of Cheng Jin's mouth were also a little bitter as he drove the car, where was his cheap disciple just talented in learning......

As for whether it will be a goof, he doesn't bother to think about it.

In this shareholding structure, he, an individual shareholder, only accounts for 12.35% of the shares, while state-owned assets account for 87.65%.

And a chip, it takes more than half a day to rub it by hand.

"The source is to convert the transmitted message into the original electrical signal, and the signal output by the source becomes the baseband signal, and the baseband signal can be divided into digital baseband signal and analog baseband signal, and the corresponding source is also divided into digital source and analog source."

"Possibly! But it's our business! Don't think too much, we can't envy this kind of day. ”

As long as he adjusts the speech tomorrow, so that Qingyun thinks that it is because of lack of money that the product is flawed and cannot be commercialized.

Qingyun's answer made Cheng Jin nod and continue to ask, "Focus on what the source is." ”

However, in the area of communication, the company's experts are in Jincheng, which is not so convenient. ”

The cigarette that he only smoked in his hand burned to the butt, Cheng Jin sighed and lit another one.

Moreover, the concept and definition are very unfriendly, and the professor needs to summarize from the book, and at this time it must be combined with the professor's courseware.

"Which buddy wrote that paragraph? So talented! ”

As for whether it can be developed...... There are always failures in scientific research.

"How do you know?"

After answering a few more questions, Qingyun closed the book and smiled

"Teacher, I'm done with my questions, do you have any more questions for me?"

For electrical communication, the message must first be converted into an electrical signal, and then the signal is sent into the channel through the sending device, and the receiving device is used at the receiving end to amplify and reverse transform the received signal, and then sent to the message to be converted into the original information. ”

What really plunged him into despair was that he forgot that Qingyun was not a scientific researcher, not an academic, but an entrepreneur.

"What is the general model of a communication system?"

It's kind of roasted on the fire.

Even sometimes, Cheng Jin himself is thinking, how good it would be if there was really a Hanxin!

Also, this kid has an unparalleled advantage over other students when it comes to learning these things.

It was a shareholders' meeting.

The state-owned assets unanimously agreed that this is pie from heaven and must be caught.

The shareholders' meeting instructed him to immediately start the industrialization operation, and the state-owned assets also stated that they would send a professional management team to help him successfully complete the commercialization of Hanxin Semiconductor.

Originally, he didn't realize this.

"But then again, I have to say, the champion is the champion, there is no one in this little composition, I can't wait to run out and buy two more packs of cigarettes at this moment."

"This little essay must be memorized! In the future, when my girlfriend says that I smoke, I will recite it to her in a righteous and strict manner! ”

Then......

After a burst of keyboard tapping, Cheng Jin looked at the blue and white porcelain picture on the homepage of Yanhuang Group on the computer, and was silent.

The legal representative is Fu Yuxi, dean of the School of Software of Huating Jiaotong University.

And the magnitude of 1 million, rubbing his hands, rubbing until he can't get out of his life.

"What are the characteristics of electronic devices made of semiconductor materials compared to traditional vacuum electronic devices?"

Cheng Jin's question made Qingyun smile, "Teacher, have you forgotten that I am still the chairman of Yanhuang Group." This identity allows me to find the right people in the company to answer my questions.

And he is a scholar of several generations, the doll has been enlightened since he was three years old, and when the talent is almost the same, he is definitely a crushing existence.

Crisis, crisis, crisis organic.

But something happened that he never expected.

However, it is inferior to vacuum devices in terms of distortion and stability. ”

He sighed and continued, "A stochastic process is a kind of process that changes randomly over time, remember, it cannot be described as an exact function of time.

You can't open your own renovation company, right?

I think it's wrong.

"Xiaoqing, is there anything you don't understand in the process of learning?"

He had just returned from a meeting at Hanxin.

Moreover, what made him feel a little unbelievable was that Qingyun had no problems at all with the highest failure rate, on the contrary, the most problematic was relatively simple communication.

He even felt that as long as he cultivated well, his son would at least surpass his cheap disciple academically.

Cheng Jin believes that the bell must be tied to the bell.

"Xiaoqing, tomorrow morning bring the books you have recently read to my office on the Minhang campus, and I will check the progress of the check."

The posters one after another directly made public opinion more hot.

At that time, it is nothing more than to persuade Qingyun to use foreign ones first, such as the chips pulled by motorcycles and mules, and speed up the research and development of Hanxin No. 2 on his side, and then Yanhuang Group will be finished using mature chips.

Listening to the conversation of the group of students in the corridor, Cheng Jin, who was passing by, frowned, and returned to his office upstairs with a calm face.

If it's a gossip forum, he will use 'Qing Yun Light Breeze', and sometimes he will use 'Qing Yun Yan Manman', 'Qing Yun Xi Cai Wei', 'Qing Yun Lang Qianying', 'Qing Yun Jian Shenyue', all of which are officially certified. ”

Now, Hanxin Semiconductor, which is a shell company, will immediately be operationalized......

But if it was just these warm-up posters, he wouldn't feel like the sky was going to fall like he did now.

For this reason, he also thought of a rhetoric, that is, to confess to Qingyun that the chip is not perfect.

His son is at the age of three or four years old, and his wife can't control it, and she can't manage it well.

Facing Cheng Jin's question, Emperor Yun blinked his eyes when he heard this, and quickly answered,

One of the major characteristics of Huaguo University's textbooks is that most of the textbooks themselves are particularly unspoken.

That cheap student had such a good time!

This answer made Cheng Jin laugh dumbly.

"It's Mr. Xiaoqing."

After all, it's just Hanxin No. 1, and the original chip is a little flawed, which is also a normal thing.

This set of statements, which can be attacked, retreated, and defended, made Cheng Jin very satisfied with his wit.

Huating Hanxin Semiconductor was established by three shareholders.

Not to mention asking questions, even if Qingyun wants to do experiments, or even encounters problems in textbooks, he can directly conduct practical operations to get the answers, and there is no need to simulate this step at all.

In other words, with the support of at least 100 million yuan of scientific research funds per year for this cheap student, it is not impossible to really reverse restore Hanxin.

After a long time, he sighed, but still took out his mobile phone and dialed the cheap student,

His computer, naturally, didn't take long to boot, and a familiar boot music came, which made him sigh and sit back in his place with a cigarette.

Isn't it okay for him to accept this list at all?

When things are at the worst they will mend.

Then their numerical features describe the mean, variance, and correlation functions, and the mean describes the swing center of the sample function......"

Cheng Jin also forgot that he is not only the dean of the School of Microelectronics of Huating Jiaotong University and the director of the National Microelectronics Laboratory, but also an individual shareholder of Huating Hanxin Semiconductor Company, the commercial operation platform of Hanxin.

Taking advantage of the computer's boot, he lit a cigarette, walked to the window, took a puff, and looked at the campus at this time in the smoke, stunned.

……

Speaking of this, Qingyun sat there and looked at Cheng Jin fixedly, "Or, teacher, do you have anything to say to me?" ”

……
