Is there a video teaching of simple and easy-to-learn signals and systems

1. Zheng Junli's version of "Signals and Systems", the lecture of the institution, for the explanation of the past exam questions of Beijing Post, is still good, which can be referred to, but the content is less and very detailed. Li Xuewu and Wu Da of Western Power's genuine version of "Analysis of Signals and Linear Systems" is for Western Power. If you just want to listen to the textbook, it is not recommended.

2. Signal and linear system Zheng Junli version is good. Zheng Junli's version of "Signals and Systems", the lecture of the institution, for the explanation of the past exam questions of Beijing Post, is still good, which can be referred to, but the content is less and very detailed.

3. If you study the genuine signal and system of Western Power Wu University, it is recommended that you watch the signal and system boutique course of Western Power.

4. cMb starts with reading books and doing exercises; reading books and doing exercises. Of course, it's better to combine it with the video. I have sorted out the relevant information, hoping to help you. I have found the latest, this year's English, mathematics and other professional courses, as well as past papers. You follow the gong public account search: Yisi Course Postgraduate Entrance Examination.

5. https://pan.baidu.com/s/1vCPuz5GBMRIK7d_vpHandQ The book "Circuits, Signals and Systems" published by Machinery Industry Press in 2010 was published by Machinery Industry in March 2010 The authors of the books published by the society are Zhang Yongrui and Gao Jianning.

6. Ha ha, I think I am qualified to talk about this question. I this yearAfter the postgraduate entrance examination, the signal score is 140. I haven't studied it at all in undergraduates. I suggest you buy Oppenheim's signal and system book first. It's simple and easy to understand.

Signal and system, as shown in the figure, please provide detailed steps.

Signals and the transformation of signals are the basis of signals and systems, which must be mastered.

Hello, the answer is shown in the figure: I'm glad to answer your question. You don't need to add any wealth. As long as you adopt it in time, it is the best reward for us. If the questioner has anything you don't understand, you can ask at any time. I will try my best to wish you progress in your studies. Thank you.

This is an incremental linear system. 5. It can be regarded as a zero input response. Usually, the linear system is dr(t)/dt+r(t)=e(t) part.The detailed process is shown in the example below. The two topics are very similar.

Question 5: How is the phase frequency angle in the phase frequency characteristics of the signal and the system calculated? The main tube bracket is 30-50 centimeters at each end of the tube, and the bracket can also be added in the middle. It's the same when turning. Only the bracket: the pipe diameter is greater than or equal to 80mm, the fixed bracket is used, the end is fixed, and the hanger is used in the middle.

Experiment one signal and time domain analysis of the system The purpose of the experiment is to observe the zero input response, zero state response and complete response of the first-order circuit with an oscilloscope. Understand and master the physical significance of each response of the first-order circuit.

Who has the "Signal and System" video tutorial, which can be downloaded.The video format is better to be normal

If you are learning the genuine signal and system of Western Power Wu University, then it is recommended that you watch the signal and system boutique course of Western Power.
