Electronic technology, the more you learn, the more boring you are, and the degree of depression is comparable to that of Shu Gao. You should be mentally prepared.

China Railway Press, Fundamentals of Pulse and Digital Circuits.

(Teaching material for electrical engineering major in technical secondary school)

Electrotechnics, Higher Education Press, Volumes 1 and 2.

(College Engineering Textbook)

China Railway Press, Electrical and Electronics.

(College Engineering Textbook)

Radio Maintenance Technology, Peking University Publishing House, Volume I, Volume II.

(General textbook for middle schools)

How does People's Posts and Telecommunications Press treat digital circuits?

Measurement and Maintenance of Radio Components in People's Posts and Telecommunications Press

The Handbook of Practical Electronic Technology published by National Defense Industry Press is relatively thick.

China Water Resources and Hydropower Press, Typical Illustrations of Practical Electricians, Volume 1.

An integrated circuit manual (I think this kind of manual is essential).

The above can be used as a reference. I started reading these books myself.

Also recommend a newspaper, electronic news.

The newspaper is quite good. I have subscribed for seven years.

It is very conducive to the accumulation of electronic technology knowledge in all aspects.

In addition, the radio station is also a monthly magazine, but it is not suitable for beginners. It is recommended to study it for a few days before seeing it.

(The above books and newspapers are not advertisements, hehe ~)

If you want to learn more deeply, I suggest reviewing the first book of advanced mathematics. Otherwise, the second half of some books may not be understood.

Digital circuit is a difficult point. Let me talk a little bit.

Learning electronic technology, digital circuit is compulsory, digital circuit is a difficult point, and you can learn it step by step in the following order.

The foundation of the pulse, logic gate and trigger in front must be laid!

1, binary and binary coding, and the conversion relationship with decimal.

2, pulse circuit (pulse signal generation, shaping, alternating. Include differential circuit, integral circuit, limiting circuit, multi-resonant oscillation circuit, monostable and bistable circuit, etc. )

3. Logic gates (AND, OR, NOT, NAND, NOR gates)

4. Trigger circuit (RS trigger, JK trigger, D and T trigger are required)

5. Combinatorial logic circuit (basic arithmetic unit, comparator, parity judging circuit, encoder, decoder and data selector)

6. Sequential logic circuits (registers are added on the basis of combinational logic circuits) such as counters and beat generators.

7, single chip microcomputer

8, the conversion between analog and digital quantity

Personal learning experience, for reference only.

After all, everyone's learning methods are different.
