Chapter 8: Staying in Autumn on September 8 (2)
In the blink of an eye, the month is over.
The investigation has officially come to an end.
Although most of the moles have been identified and dealt with accordingly, the aftermath of this matter is far from over.
Sun Mingrui is a good example.
Since he was angry with Liu Meng last time, he has been constantly looking for faults. Liu Xing's daily affairs now are nothing else, just staring at him. There was a strike at every turn, an explosion at every turn, not only the communications department, but other departments were also affected by him.
But Sun Mingrui is not afraid, their department has this privilege.
This privilege was given by the emperor.
And it's permanent.
Unless, Liu Meng, they can find a way to replace him. This Sun Mingrui is not a character that can be replaced casually, when Liu Chengen was still there, he improved the technology of firearms, transformed and invented a new generation of motorized rifles, and pistols. Although after that, there was nothing to take it for, but just these two things were enough to make him famous in history.
Such a person would not be offended even by the emperor.
Liu Xing also has no choice, although Sun Mingrui is making trouble, it is all within his rights, Liu Xing can't catch his handle, so he can only keep an eye on it. Thanks to the Ministry of Communications, Liu Xing really can't help.
Because of Sun Mingrui's interference, the restoration of the Ministry of Communications was carried out very hard, but fortunately, it was only a front. Otherwise, I was really disturbed by him, and I couldn't do anything for three months.
Liu Meng had already started work at his house with his small team.
When Luan Mengyu came, Liu Ru was still very happy, and looked at her daughter-in-law's expression. pays more attention to Luan Mengyu than Liu Mengdu.
Liu Meng explained a few times, but he couldn't explain clearly, so he was too lazy to explain.
Anyway, if you don't explain it, you can't change the result, Luan Mengyu shouldn't like a boy like him.
To be precise, there are very few people here who like a boy like him. The main thing is that there is no sense of security, in this era when wars often break out, it is still more popular to be tall and powerful, he is a boy like him, it's okay to play, and there are still relatively few people who choose to be a husband.
In addition to the different views on mate selection in this world, the main thing is that Luan Mengyu seems to be very cold to him.
Especially at this tense time, I am afraid that only Liu Ru is thinking about finding a daughter-in-law for Liu Meng all day long, which makes Liu Meng very helpless, and he looks at Luan Mengyu with an apologetic expression.
Fortunately, they don't have to take care of anything here, and the food, clothing, housing and transportation are all arranged by Liu Ru clearly, so that the development progress is very fast. Although they have been researching, no one knows what they are doing except Liu Meng. What's the use of studying this thing called a wave?
Liu Meng didn't explain in advance, because he knew that if he said what he thought, no one would believe it, so he simply didn't tell them, and then told them when it was almost done.
Luan Mengyu and the others have been waiting for Liu Meng's explanation.
With the passage of time, seeing that the first phase of research and development has come to an end, Liu Meng still did not reveal half a word.
A few people couldn't help it, and their hearts were itching. Wait, wait, wait, and finally the test was successful. They wanted to see what kind of medicine was sold in Liu Meng's gourd. Liu Meng seems to have been prepared for a long time and brought all the previous R&D materials here.
Luan Mengyu was the first to go up and hammer him.
"When did you back up all these materials?" After the hammer, Luan Mengyu asked.
Liu Meng said as a matter of course: "These materials have been backed up since the first day I went. ”
"Did you already know that this was going to happen, or did you arrange the fire?" Luan Mengyu asked.
Liu Mengyi covered his head: "Why do you all think so, I have nothing to do with burning information, those are all first-hand information, which is precious and meaningful." In the future, it will enter the museum for future generations to admire. I do this just to be safe. Don't you think it's dangerous to simply pile up information there? Even if no one takes the initiative to burn it, what if there is an accident. It's best to have a few copies of this kind of information just in case. ”
"Is that what it looks like?"
A few people didn't dig deeper. In fact, these materials were originally meant to be backed up and hidden, but they didn't know what they could study, so they simply put them there, and when they really researched them, it was not too late to back them up.
After explaining, Liu Meng continued: "The things we did before, although they created a precedent, but they didn't have any use, forgive me directly, that kind of thing was developed, and in the end it just became the plaything of those famous nobles." Is this the original intention of my development, of course not. The things we develop should meet the needs, meet the market, and bring benefits to the society and the country, and such research and development is valuable and what we want to do. ”
"That's why I asked you to develop this thing."
"You've never been curious, this wave can be transmitted, but is there any use?"
"I'm telling you now, what you're doing now is what you are doing is making history and creating miracles. This thing is called RF, and I like to call it 1G, the first generation. These waves can transmit data so that my sound signal can be transmitted to another device through these waves and released. ”
Ding Xiaofeng couldn't help but say, "But how to load the data." ”
"Data, as I said before, can be represented by a switch, or as you might call it, 0,1. 0,1 can be combined into a lot of things, now I'm going to tell you about binary ......"
After Liu Meng explained binary, several people were surprised, they never thought that just a simple 0,1 could explain everything in the world.
Liu Meng didn't tell them that this was the magic of computers.
"The wave that we are developing now, I call it a sine wave, and the sine wave is composed of amplitude, phase, frequency. The period from the highest to the next peak is called a cycle. We can represent 0 or 1 by the amplitude, low means 0, and 1 means high. ”
"This makes it possible to load 0,1 on the carrier, and in this case, I want to call it modulation, which is caused by a change in amplitude, is called amplitude modulation."
These basic theoretical knowledge are very difficult to explain, and Rao is Liu Meng has learned it once, and he has been engaged in this job and has not been able to explain it very clearly. But enough for them.
Liu Meng just said it once, and they understood the approximation.
Waiting for Liu Meng to finish explaining, they all had expressions of sudden realization.
Liu Meng didn't think they were pretending, they must have understood. The modulation and filtering of waveforms is not an easy task, although the general direction is there, but the details are the factors that determine success or failure.
Amplitude modulation is not a good way to transmit voice, because the amount of data converted into speech is large, and the anti-interference ability of amplitude modulation is not good. The transmission distance will certainly not be far.
But Liu Meng knew that Rome was not built in a day, and he couldn't eat hot tofu in a hurry. Amplitude modulation is relatively simple and much easier, and you have to give those people hope first. They're going to keep trying.
I just want to go to a place, you see it, even if you are tired, you will insist on it. The most feared thing is to keep walking and have nothing.
Several of them were workaholics, and after Liu Meng told them the method, several of them began to study it.
Liu Meng suddenly envied them, these people were real talents.
He was just a slacker standing on the shoulders of giants, who had seen the face of the world, and now he only recounted it. Those people, through his vague narrative, realized these things little by little, and turned them into real things.
