I am also a major in this field, but we attach too much importance to embedded technology. I also want to spend time learning basic electronic circuits. My previous module electronics were terrible, but I don't think it has anything to do with the microprocessor behind me ... Math is very good, but I don't know what it is for ... I think you must have a deep understanding of basic electronic circuits if you want to be a module electronics engineer. I recommend you to read some foreign electronic circuit textbooks. I have read some, and I think it is better than that. Digital circuits are also very important, and this domestic textbook is enough; There are also RF circuit design and application, and there are also very good blue covers abroad; It's best to find books on electronic design for college students, which are full of practical circuits, and I feel very good personally.

Another professional direction is also super hot, that is, the design of integrated circuits, with analog electronics being the most advanced. Some good universities have made it an undergraduate major. If this is a graduate student, the salary is invincible. In addition to the materials recommended in the appeal, there are also foreign integrated circuit books that must be read. There are books and training materials published by internationally renowned IC companies like TI. Although it is an electronic text, it has gained a lot from reading it. I have seen an integrated circuit design of TI before. Starting from the most primitive ohm's law, we abandoned a lot of useless circuit knowledge and went directly to the topic, which was very thorough. Unfortunately, it's an e-text, so I don't understand it very much. ....
