2. The course of Electrical and Electronic Technology has a short history.

There are many loopholes in the teaching materials of electrical and electronic technology.

Example 1: Current and voltage are correlated and uncorrelated for a while, which makes people feel unpredictable;

Example 2: Balancing minority carrier drift current with one millionth of multi-carrier diffusion current is simply more absurd than throwing stones at eggs, which harms generation after generation.

Example 3: I wonder how big the operating point of the amplifier is?

Example 4: I don't know the maximum undistorted output voltage amplitude of transistor amplifier. After learning the amplifier, I was still in the dark.

4. Many people have improved the compilation of teaching materials of electrical and electronic technology. The most typical ones are the new system characteristic electrical technology textbook "Electrical Technology" edited by Yuan Zengmin and the new system characteristic analog electronic technology textbook "Concise Course of Analog Electronic Technology", which have been published for three consecutive editions and have been adopted by dozens of universities in China, and achieved good teaching results. Yin Fu's electro-jet training has achieved good results and students generally like it.
