Electronic engineering is also called "weak current technology" or "information technology". It can be further subdivided into electrical measurement technology, adjustment technology and electronic technology.

Electronic engineering is a sub-category of electrical engineering, which is oriented to the electronic field. Today, its research object has gone beyond the electronic field.

The application forms of electronic engineering include electrical equipment and various electrical switches using control technology, measurement technology, adjustment technology, computer technology and even information technology.

The main research fields of electronic engineering are circuits and systems, communication, electromagnetic field and microwave technology, and digital signal processing.
