AI Technical Summary

Problems solved by technology

At present, the signal detection and processing experimental devices are mainly for electrical majors such as computer, communication, microelectronics and electronic engineering. The design of the signal detection and processing system is complicated, and it takes more energy to build the electronic system and troubleshoot, which is not strong for electronic technology. Students majoring in electromechanical have put forward higher requirements, which to some extent hinders the development of students' interest in electronics, which in turn affects the cultivation of students' innovative ability and practical ability.

So far, there is no mixed-signal detection and processing experimental device suitable for electromechanical majors, which is convenient for students to quickly grasp the comprehensive knowledge of electronic systems and expand the application of electronic system design in non-electrical professional fields
