"According to this, the volt-ampere relationship of circuit components can be expressed in the complex frequency domain, that is, resistive component: V=RI, inductive component: V=sLI, capacitive component: I=sCV. If resistor R and capacitor C are connected in series , and derive the voltage at both ends of the capacitor as the output, then the "voltage division formula" can be used to derive the transfer function of the system as H(s)=(1/RC)/(s+(1/RC)), so the response The Laplace transform Y(s) is equal to the product of the excitation Laplace transform X(s) and the transfer function H(s), that is, Y(s)=X(s)H(s)”
"The Laplace transform solves homogeneous differential equations with constant variables and can convert the differential equations into algebraic equations so that the problem can be solved. The Laplace transform converts a signal from the time domain to the complex frequency domain (s domain) Come up and express"
"Very good, well done. I hope to come to class more often in the future."
Shao Zhen’s explanation shocked the professor, and Shao Zhen also felt proud of himself.
Vitality: 20 (20)
Mental strength: 20 (21)
True temperament: 20 (20)
It may be due to mental overflow.
"What is this game civilization all about? Why is there an anti-expansion army?"
"Shao Zhen, what are you thinking about?"
The squad leader next to him poked Zhao Wuji and said
"It seems like your fiancée hasn't seen you for a long time?"
Zhao Wuji glanced back and said
"She participated in a technical project and wanted to keep it secret. After decrypting it, she came to me."
"I heard you guys are going to a movie tonight?"
"Well, let's go with everyone from the dormitory. Why are you so well-informed?"
"I'll go with you, okay? That female moon person is from our dormitory."
"Call everyone in your dormitory"
"you please?"
"No problem, I'll please"
"It is said that the moon man is also engaged. Now he invites the female moon man to watch a movie. Is it appropriate?"
"how could I know"
"You are the core of your dormitory, how could you not know?"
"No way, I'm not even the dormitory leader."
"You are an outstanding person in our class, and you don't know that?"
"have no idea"
“Not many people can participate in a Mars expedition within a few days of starting school.”
"It was a coincidence."
"Is it a coincidence that the anti-expansion army assassinated you?"
"Well, mostly yes."
"The assassination was not successful, too?"
"Yes"
"I heard that the anti-expansion forces have a huge influence. Aren't you worried?"
"If worrying is useful, then I will worry."
"Haha, worrying is useful. For example, when watching a movie, it is safe if you don't leave the campus, but it is not safe if you leave the campus. There are movie theaters both inside and outside the campus."
“Okay, I understand, I’ll watch it at the cinema on campus tonight.”
"Haha, this is your own decision, but what if the two moon people don't want to?"
"Beautiful squad leader, on behalf of my dormitory, I invite your dormitory to reserve the theater to watch a movie. How about that?"
"make a deal"
"Shao Zhen, can you reserve the theater for everyone to watch a movie and let us join in? Anyway, one more person is not more than me, and one person less than me is not less."
A girl next to me who didn’t know which planet she came from said
"She is the beauty He Yu from the isolation class, from the ninth cantilever and star of Orion."
"It doesn't have to be complicated, just call me He Yu"
"With such a long distance, it doesn't mean that the wormhole is not stable. You think it's so risky?"
"Wormholes are unstable, but you can always get through by jumping a few more times."
"How do you understand it specifically?"
"Well, it's just a random return in the topology array. Although it takes a little time, if you have enough time, you can always get there."
"Well, I still don't quite understand."
"Well, I don't quite understand it, but the technical principle is this, and the result is successful."
"Then you want to go back, is this the same?"
"It's almost the same, but the wormholes in the solar system have many exits and relatively few entrances. It's easy to come in but difficult to go back. So I plan to go back after graduating from college in four years. I hope you two Blue Star people will take good care of you."
"All right"
