About the circuit review method:

Second, do more real questions, that is, to ponder the past real questions of the school's exam, and see if the focus of the questions is on the first.

3. Refer to the postgraduate examination papers of the same level of colleges and universities, and many schools will learn from each other, so it is also beneficial to look at the circuit papers of other schools.

Phase 1: Architecture.

From the end of October to the beginning of November, you don't need to do the exercises in the back to read "Circuits", you can summarize the knowledge points of each chapter by yourself and then read the example questions thoroughly. At this time, you should have the structure of the entire circuit book in your head, which is convenient for the next step of review.

Stage 2: Deeply cultivate the circuit exercises.

From the beginning of November to the end of November, I will do all the important exercises at the end of each chapter of the circuit, and of course, I will do it in combination with the exercises of "Circuits" to solve the book. At this time, you should master the basic problem-solving methods and apply them proficiently.

The first and second stages are mainly based on circuit books to review professional courses, and then mainly on professional examination papers.

Stage 3: Research notes and test papers.

When we have mastered the basic structure and problem solving methods of the circuit book, we will focus on the professional test papers to review.

Do the professional test papers three to four times in December, and pay attention to three points in the process of doing it:

1. Summarize various types of questions and review them in combination with circuit books.

2. Study the test questions in the notes and familiarize yourself with the solution methods of these test questions.

3. Pay attention to the summary.

Stage 4: Harvesting.

I believe that everyone will be sure when it comes to the graduate school entrance examination, but you should remember to read the professional test papers and summary notes two weeks before the exam to check and fill in the gaps.

For the postgraduate examination circuit, you can first look at the examination style of the school for the circuit, and then specifically understand the type of questions of the colleges and universities you are applying for, what are the question types, for the review, you can first carry out the overall learning, and then by doing a large number of exercises, check and fill in the gaps, the rest is to study the real questions well, and the real questions do well to play a decisive role in the circuit score. Do the professional test papers three or four times in December, pay attention to three points in the process of doing it1, summarize various types of questions and then review them in combination with the circuit book 2, study the test questions in the notes, and be familiar with the solution methods of these test questions. 3. Pay attention to the summary.

In January, everyone is going to the battlefield, and I believe that everyone will be sure of the professional course at that time, but I want to remind you that two weeks before the exam, you must remember to read the professional test papers and your own summary notes, and it is very important to check and fill in the gaps.

Do something that seems to make sense but doesn't actually help. For example, some people are accustomed to doing past year questions a few days before the exam, thinking that this will help you understand your level and increase your confidence, but in fact it will not help you improve your overall score. Because after the review, the basic level of the person has been set, and the good results of the mock answer sheet may only be because you have this level, which will naturally not help you improve your confidence, and if you do not answer well, it will hit your confidence, so why bother?

And if you don't perform well or overdo in the simulation, it will make you misjudge the real exam. Some people want to know how long it takes to master the answering questions through this practice, which is very wrong, because you should have gradually familiarized yourself with the allocation of answering time during the exam during the revision process, so that you can really develop good habits.

There are many directions, automation classes need to test circuits, and netizens recommend Mr. Yan's courses for postgraduate circuits, and here is a copy of the teacher's latest postgraduate circuit information to share with you;

There are many directions, and the automation class needs to test the circuit

Integrated circuit major, Sun Yat-sen University has it, you can sign up now.

You can take the 4 second-level disciplines under the first-level discipline electronic science and technology.

1.Do test papers: Do more real questions and mock test papers to test your mastery and find out your own shortcomings. For unfamiliar knowledge points and problems, it is necessary to re-learn them in combination with the teaching materials.

2.Find information: You can find some circuit information to supplement. For example, you can take a look at some classic circuit design cases, or learn about some tips and methods for laboratory practice.

3.Attend training courses: If time and financial conditions permit, you can sign up for some training courses for postgraduate circuits. In this way, you can not only review systematically, but also get guidance and answer questions from professional teachers.

In short, the study of the postgraduate entrance examination circuit needs to be constantly emphasized, accept a variety of channels and methods of learning and practice, and constantly accumulate experience and improve one's ability in order to better cope with the exam.

1 If you just follow the textbook, it is not enough, because the difficulty of the graduate school entrance examination is very high, and a lot of practice is required.

2 Because circuit is a highly practical subject, it requires continuous hands-on practice and mastery of practical skills, and only in this way can you truly master this subject.

3 I suggest that you can participate in some offline or online tutorial classes, follow the teacher's teaching and guidance, and do a lot of practice and practice, so that Tan Zhengming can improve his mastery and comprehension ability, so as to better prepare for the postgraduate entrance examination.

At the same time, you can read more books on circuits to deepen your understanding and knowledge.

For the postgraduate entrance examination, if you want to follow the textbook, you must first clarify the purpose of learning, as well as the core content of the postgraduate examination, understand the structure and content of the textbook, and clarify the focus of learning and the selection skills, so as to effectively complete the study of the textbook. Next, it is necessary to formulate a complete study plan, and in the learning process, it is necessary to make a good summary, review the key knowledge points in time, and use them comprehensively to deepen your understanding. At the same time, you can combine the postgraduate examination materials to make a summary of understanding, summarize key knowledge points, and make corresponding application exercises to improve your understanding and application ability.

Finally, it is necessary to maintain good study habits, develop regular study, and make your study plan more orderly and efficient, so that you can finish the textbooks more seriously with the elderly, and finally achieve the goal of the postgraduate entrance examination.

The postgraduate circuit can be divided into three parts: basic theory, experimental practice and detailed answers. First of all, to be familiar with the basic theory, it is necessary to master the basic concepts of circuit knowledge, the drawing method of circuit diagram, the analysis method and experimental principle of various circuits.

Secondly, to be familiar with experimental practice, it is necessary to master the use of experimental instruments, the operation methods of experimental techniques and the analysis methods of experimental results. Finally, in order to master the detailed answers, it is necessary to master the solution methods of different circuits, be familiar with the skills in circuit analysis, be familiar with the drawing methods of circuit diagrams, and be familiar with the design and analysis methods of various circuits. In short, candidates are required to have a strong theoretical foundation, experimental skills and dialectical analysis ability, and after combining the teaching materials, doing more experiments and summarizing experimental experience, in order to better master the postgraduate circuit.

The most important thing is to grasp the overall framework, figure out the basic concepts, and then use the framework to understand each specific content, and use practical examples to deepen your understanding, form your own understanding and mastery, and finally use the practice of the situation to test your own learning effect and level.

<> circuit equivalent to a phasor model, above. US (phasor) = 6 2 0°V = 3 2 0°V, =1000rad s.

ic（t）=。

So: ic (phasor) = .

xc=1/（ωc）=1/（1000×50/1000000）=20（ω）

So: uc (phasor) = ic (phasor) (jxc) = .

According to KVL: US (phasor) = U1 (phasor) + UC (phasor).

3 2 0 ° = u1 (phasor) + 2 0 °, u1 (phasor) = 2 2 0 °V.

i(phasor) = u1 (phasor) r1 = (2 2 r1) 0°.

The current I (phasor) and UC (phasor) are 0° in the same phase, and the impedance of the parallel branch is Z, then:

uc(phasor) = i (phasor) z, the imaginary part of z is zero, and:

So: xl -20xl+100=0, xl=10( )l=xl=10 1000=.

So: z=20 200 [100+(10-20)]4000 (100+100)=20( ).

i (phasor) = uc (phasor) z= 2 0° 20=.

i（t）=。

r1 = u1 (phasor) i (phasor) = 2 2 0°
