In 1978, I was admitted to Harbin Institute of Technology

Chapter 83: What’s the point of having an advanced design? We can’t build it!
"Ah? Xie Wei asked for so much? I really didn't know!"

Du Guowang thought the principal wanted to see him for something else, but when he heard Xie Wei asking for 170 million yuan in funding, he couldn't help but be shocked.

Doesn't this kid know how huge a sum of money this is?
Li Rui kept staring at Du Guowang's reaction, and was surprised. He was not pretending.

Do you really think too much?
"You really didn't instigate Xie Wei to ask for it?"

Li Rui looked at Du Guowang with suspicion.

"Heaven and earth, conscience!"

Du Guowang looked more wronged than Dou E, and was stunned. "That's not right, President. The 20 yuan you approved for the Department of Mechanical and Electrical Engineering was spent on the Computer and Chemistry departments. There is still 120 million yuan left. You have to make up for it for me, right?"

"Get out, I have work to do!"

"Come on, let's talk it over..."

"Crack~"

"Get out!"

“Hua~la…”

The desk, which had not yet been repaired, fell apart and fell to the ground again.

"I didn't take the photo this time, so don't try to deduct my money! I have something else to do, so I'll leave first. I'll come back to discuss the funding issue with you after I'm done!"

Seeing the desk collapse again, Du Guowang hurriedly slipped away.

"Good! We have to keep this desk!"

Du Guowang, who had always been shameless and dared to block the principal's office for funding, fled in panic. Looking at the desk that collapsed to the ground, Principal Li was very satisfied, and then sighed, "It's just a little embarrassing!"

"Wu Tao, Wu Tao..."

Just as I was about to ask Wu Tao to find someone from the logistics department to repair it, I realized that Wu Tao had already left.

"What on earth does this kid want to do? 170 million in funding!"

"Hey, Principal Li, your conditions are really tough! Why don't you change your desk even though it's in this state?"

Just as Li Rui was wondering what Xie Wei wanted such a large sum of money for, Xie Jianguo's voice was heard at the door.

"..."

Principal Li was suddenly embarrassed.

"To learn radio, we must first understand the basic structure of a radio station. The key lies in the modulator and power amplifier of the transmitting part; the antenna, tuner, demodulator, etc. of the receiving system..."

Xie Wei drew a simple diagram of the basic structure of the radio station on the blackboard and explained it to the newly formed project team.

The original owner had done it before, so he didn't hide it anymore.

"For each function, the silicon 2-watt and large 81 drawings in your hands have detailed descriptions..."

"The radio is used to receive AM frequency bands ranging from 530kHz to 1710kHz and FM frequency bands ranging from 88MHz to 108MHz. The difference between the two is mainly in the transmission power, propagation range, etc...."

"Tsk tsk tsk, you are not doing your job properly all day long. Although a radio is also a wireless device, it is different from a radio station."

The other project members listened with great interest, but Liang Hongbin on the side began to pour cold water on them.

His words immediately made the project team members who were listening carefully to Xie Wei's introduction and taking notes look at him.

"Teacher Liang, why don't you go and do your thing first?"

Xie Wei looked at Liang Hongbin unhappily.

He didn't care that this was Liang Hongbin's office and just kicked the person out.

Liang Hongbin looked at Xie Wei in astonishment, "This is my office!"

The radio project team consisted of not only the four people from the experimental class, but Liang Hongbin also selected four students with solid foundation from the workers, peasants and soldiers majoring in the radio major to express his support for Xie Wei's radio station project.

Liang Hongbin doesn't care whether he can do it or not.

He was eager to fail.

If he fails, Xie Wei can focus on chemistry and physics research.

As one of the first students in the mechanics class of USTC, Liang Hongbin not only studies mechanics, but also has a good level of chemistry.

High explosives involve not only chemistry but also physics.

Physical chemistry, based on physical theories and experimental techniques, explores, summarizes and studies the basic laws and theories of chemistry. In Liang Hongbin's view, whether it is physics or chemistry, the key is to develop high-energy fuels with higher specific impulse, lower cost and better safety, so that rockets can have faster speeds and stronger carrying capacity.

Unexpectedly, Xie Wei, a member of the radio station team, started talking about radio!
Isn't it a waste of time and money?
Looking at Liang Hongbin's attitude, how could Xie Wei be polite?

"I know. You're not very busy? How about doing something else first?"

"This is my office!"

Liang Hongbin emphasized again that he wanted Xie Wei to reorganize his words before talking to him again.

The boy is so inflated!
Kick yourself out of your own office?

"You gave me this project! How about I go outside and find an open space with everyone else to continue the discussion?"

Xie Wei raised his eyebrows, not caring about Liang Hongbin's reaction at all.

"Okay! You are awesome!"

The radio station that Xie Wei was required to build was for military use. How could Liang Hongbin dare to let him set up a blackboard outside to take classes like other majors that did not have classrooms?

With no other choice, he had to leave his office.

"Let's continue!"

Ignoring the stunned faces of the project team members, Xie Wei tapped the blackboard with the handout in his hand to bring everyone back to their senses.

"Both are signal receiving devices, but the radio station receives shortwave signals with a frequency range of 3MHz to 30MHz..."

"The radio has a simple structure and high requirements for sound quality. The radio station needs to pay more attention to communication performance and stability to ensure the quality and transmission distance of the received and sent signals..."

"In fact, the project is not as difficult as everyone imagines. All we have to do is integrate the original various electrical components and circuits into one circuit, and enhance the function through signal processing of circuits and single-chip microcomputers..."

"Next, we'll practice with the radio."

When setting up a radio station, Xie Wei brought out the radio to talk about something.

It is really a helpless move.

The entire team has a very poor foundation and has to learn while studying.

Xie Wei was also very clear that this was normal in the country these days. Not to mention anything else, the National University of Defense Technology's billion-times computer project was also in this state.

Over the next decade, the radio market was very large, with a simple structure and much easier to control than radio stations.

"Student Mo Lingyu, you were a communications soldier before, and you are familiar with radio stations. You will be responsible for leading everyone to discuss, go to the radio laboratory to test various components, and complete detailed designs and improvements..."

"I?"

Mo Lingyu didn't expect that after Xie Wei explained the basic structure, he would let him take charge.

I'm just a communications soldier!

Before she could react, Xie Wei had already left Liang Hongbin's office.

"Boy, I thought you wouldn't show up if I didn't come to find you."

In the Computer Science Department, Yu Guofeng looked at Xie Wei and said unhappily, "The entire Computer Science Department is busy with your project, but you didn't even show up!"

"I'm here to make money. Director Yu, have you finished the single-chip microcomputer design work?"

Xie Wei explained with a smile.

Yu Guofeng's light-hearted tone of rebuke made Xie Wei feel that there was good news.

"You have already come up with the architecture. All we need to do is to improve the circuit according to the function. The design is actually much simpler. We just need to connect the transistors through the circuit."

Yu Guofeng looked at Xie Wei in front of him and wanted to cut open his head to see how his brain looked.

Even the chip architecture can be easily figured out.

In the eyes of professionals like Yu Guofeng, the MIPS architecture proposed by Xie Wei is not only a brand-new architecture, but also has unlimited and broad development prospects.

"how?"

Seeing that there was not much joy on Yu Guofeng's face, Xie Wei's heart skipped a beat.

Is it possible, what's the problem?
"The design is fine, but our laboratory may not be able to manufacture it. I don't know who in the country can manufacture it..."

what?
Xie Wei was dumbfounded.
