The major of electronic information engineering is mainly to learn basic circuit knowledge and master the methods of processing information with computers. First of all, they should have solid mathematical knowledge and high requirements for physics, mainly in electricity; We should learn many basic courses such as circuit knowledge, electronic technology, signal and system, computer control principle, communication principle, etc. Learning electronic information engineering requires you to design and connect some circuits by yourself and conduct experiments with computers. The requirements for manual operation and use of tools are also high. For example, you can connect the circuit of the sensor yourself, set up a small communication system with a computer, visit the electronic and information processing equipment of some large companies, and understand mobile phone signals and cable TV.
