"Then do you estimate that this signal filter, give you the best parts to do, and the finished product can filter the radar signal?" Zhao Changfeng asked suddenly.

Hearing the word "radar", the army was still very sensitive and did not answer immediately, but picked up the yellowed notebook on the workbench, carefully glanced at the circuit diagram on it, and then asked: "There are some words, I don't know if I can say them?" ”

"Say it!" Zhao Changfeng also estimated in his heart what the army was going to say, so he said very shamefully.

Although there is no introduction, the army is not a completely sophisticated person, some simple observations, he still understands, and also estimates that Zhao Changfeng is the highest commander among these people.

Since Zhao Changfeng has said it, he no longer hesitates, and said calmly: "I don't know much about foreign radars, but some of our domestic radars, I know that there is a little defect, according to that defect, the signal filter I designed, if the quality of the components is excellent, it should be able to filter out the signal of these radars." ”

"Can you find a way to help us fill in the gaps in these radars?" Zhao Changfeng said his intention at this time.

The army first glanced at Fu Xin, saw that Fu Xin just nodded at him, then turned around, picked up the notebook in his hand, flipped through it a few times, turned to a page full of circuit diagrams, looked at the information on it carefully, then closed his eyes, thought about it, and said: "I can't guarantee that I will be able to make it, but I can try to design a signal booster to fill this shortcoming." But I don't dare to pack the ticket to make it. After all, it's always easier to destroy than to build, and I can make a signal filter very quickly, but not a signal booster very quickly. ”

"Then you estimate, you are about to be sure that you can do it. We can provide you with the best research conditions, all kinds of good components, as long as you need, we can help you get them. Zhao Changfeng said with some joy.

The army did not answer, but stretched out four fingers and gestured, which means four into one.

"You're saying you're 40 percent sure?" This kind of thing, Zhao Changfeng didn't dare to make up his guess at will, so he asked it very rigorously.

"Hmm!" Army nodded and said.

"But......" The army looked at Fu Xin and said.

When Zhao Changfeng heard this sentence of "but", his heart couldn't help but be mentioned, and then asked, "But what?" ”

After thinking about it, the army decided to say it, so he looked at Fu Xin and said: "If Brother Fu is also involved, I estimate that there will be seventy or eighty percent of me, Brother Fu's technology accumulation, which is much stronger than me!" There are many things that I am not as good as him, and from him, I can get a lot of inspiration. ”

"Oh?" Zhao Changfeng didn't expect the army to deal with the new evaluation would be so high, so he looked at Fu Xin.

Fu Xin also had to stand up at this time, and said: "If there is a place where you need me, you can find me, as long as I can help, I will definitely help." After all, as you said before, if it succeeds, this signal booster will be handed over to my electronic component factory to produce it. ”

"Good! That's it! Lao Liu, you are familiar with Comrade Fu Xin, and you also understand this, so you can discuss the specific implementation plan with them! "After all, Zhao Changfeng is the highest level among this group of people, and the highest level must have the appearance of the highest level, so he is only responsible for decision-making, and he doesn't care about the specific plan, anyway, he doesn't understand.

……

"This resistor should be placed in this place, you see, here, so that this line does not short-circuit! Moreover, there is also an advantage to putting it here, which can make the triode here work more efficiently. Liu Xiaojun pointed to the unfinished circuit diagram designed by him, Fu Xin, and the three of the army, and said.

At this time, Fu Xin and the other three were already working on the signal booster, and the three of them all ate and lived in an office in the garrison, so that it was for the convenience of research, after all, if you need any components temporarily, you can find someone to do it here, without going around in a big circle. The second is to keep it secret, Zhao Changfeng still has this sense of confidentiality.

"That's not right, right? If the efficiency of the transistor becomes higher, it may be good for the part, but on the whole, the VSWR will change, which will affect the effective power transmission. "The army thought about it for a while, but still put forward a different opinion on this issue.

Fu Xin thought for a while, pointed to the picture and said: "I think it's better to put it here, although it will affect the gain of this part, but the gain is adjustable, and we will start with other things, and adjust the gain here, so as to ensure that this line is not short-circuited, and it can also ensure that the VSWR does not change anything, and push our original design to." ”

"I think it's doable." It's no big deal that his plan was denied, after all, his plan was flawed. Liu Xiaojun said approvingly.

"Hmm!" The Army agreed.

Seeing that the two of them had no opinions, the circuit design of this part was also decided, and then discussed the others, Fu Xin pointed to an automatic review control circuit on the drawing and said: "I think this design is not necessary, I feel a little redundant, since it is an enhancer, we don't need to limit the width, so it's a bit redundant." ”

"Well, I don't need to see this row of filters connected in series with the magnifying tube, because in the use of Shi Ji, the interference signal generated will be very large, and with this filter, I don't think it will be able to filter the interference signal." Jun Jun nodded, pointing to the row of filters that Liu Xiaojun had joined before and the magnifying tube in series.

"yes, it looks like we have a lot of problems." Liu Xiaojun lamented that they had been here for eight days, but even half of the circuit diagram was only almost complete.

This signal booster is really a headache, if it weren't for Fu Xin, an expert, who didn't mention it on the side, maybe the progress would be slower.

However, Fu Xin doesn't know much about this signal booster, of course, it's not that he doesn't understand the signal booster, but he doesn't know much about this old-fashioned signal booster.

After all, for his previous life, it is something that has been outdated for a long time, many technologies have been eliminated, and they are completely useless, and it is useless to learn, after all, Fu Xin is mainly engaged in mechanical manufacturing and automation, so Fu Xin does not know too much about these eliminated technologies.

"Let's go eat first, I'm hungry, let's think about it for a while, this thing, it's useless to be in a hurry, it's not something that can be made in a while." Fu Xin proposed.

"Okay!" The army and Liu Xiaojun, who were also hungry, also agreed, saying that it was already more than one o'clock in the afternoon at this time, and they had not yet eaten lunch.

As soon as the three of them walked into the canteen, the officers and men of the cooking squad brought out the food that had been kept warm on the steamer.

All three of them were hungry, and they all grabbed the food in front of them!

While eating, Fu Xin suddenly said, "I thought of it!" I didn't expect it, why didn't I think of such a simple question? ”

"What didn't you expect?" The food in the army's mouth has not been swallowed yet, he is also eating while thinking about the problem, and now when he heard Fu Xin say this, he immediately became interested. While chewing on his food, he said inarticulately.

"I wondered, can we boost the signal in a snatching way?" Fu Xin stopped the chopsticks in his hand, stretched out his head, and said to the army and Liu Xiaojun who were sitting on both sides.

"How?" Liu Xiaojun was also interested, and quickly swallowed the food in his mouth, and then asked with some excitement.

Fu Xin said: "We can design a signal conversion device on it to capture the disturbing garbage signals in the air, so that our signals are enhanced and the garbage signals in the air are weakened." ”

"Well, let's go back and think about it." Although the army felt that what Fu Xin said was vaguely correct, he did not dare to confirm it, after all, the need for high scientific research is rigor, and this is a necessary quality for scientific researchers.

……

"I didn't expect it to be feasible!" After some formula derivation, the three of them finally calculated that the plan proposed by Fu Xin was feasible.

This makes no progress for half a day today, and the three people who have been discussing the loopholes are overjoyed, and now they can do it, as long as they can draw the circuit diagram roughly, specifically, to verify, to fill, it will become.

"Anyway, I didn't draw a picture today, just don't draw it, write it down first, let's think about it tomorrow, I think we should think about the antenna next!" Fu Xin proposed.

"As for the antenna, I have some ideas! I think the long-wire antenna is better, and if the ground is placed in parallel, it has the good directivity of the Yagi antenna, and it has a higher gain than the dipole antenna; If it is placed perpendicular to the ground, it does not take up space and can also have a good radiation effect. The army is more proficient in this, he thought about it and said.

"No, if you're outdoors, the suction cup antenna number, the suction cup antenna can receive the signal very well, which is very important!" Fu Xin said.

"What is a suction cup antenna?" Lu Jun and Liu Xiaojun asked at the same time.

"Sucker antennas are the kind that roll into a circle larger than the other." Fu Xin suddenly realized that he was ahead of his time, but there was one thing he didn't say, that is, coaxial cable, which is better! But obviously, this era does not.

"Oh! The principle is somewhat similar to the long-term world, both of which are to stretch the antenna as much as possible! Liu Xiaojun also figured it out.

"Yes, that's it. And it's not that I'm bragging, the suction cup antenna is much better than the long-term world, and it is a lot easier to carry! The Army was also on the sidelines to make peace.

ps: Chapter 2 is late, I hope you forgive me! Ask for recommendation tickets, Sanjiang tickets!
