Modular Simulation Teaching of Analog Electronic Technology Based on sEMG Signal Acquisition Circuit

Analog electronic technology is a basic course in the fields of automation, electronic information, communication and other majors in modern colleges and universities. It is a discipline that studies analog circuits that process analog signals. Based on the concept of modular teaching, the teaching model centered on imparting knowledge is transformed into a modularized teaching model centered on application-driven teaching, which enables beginners to have a deeper understanding of analog electronic technology courses more quickly and effectively. This paper takes the sEMG acquisition circuit as an example. The course content is divided into four major modules, power supply module, signal amplification module, filter module, and simulation module, thus training beginner's practical operation ability and understanding the applications of analog electronic technology, to lay the foundation for later study.
