Abstract

The invention relates to a multi-person voter device for analog electronic technology teaching, and belongs to the technical field of electronics. The wide application of an operational amplificationelectric appliance is one of important teaching contents of an analog electronic technology; in order to improve the teaching effect of the operational amplifier content, a multi-person voter device composed of an LM358, a self-locking switch, a dial switch, a resistor and a light emitting diode is designed. The voter device can adjust different consent people according to requirements, can be configured into a multi-person voter with 1-8 persons, is applied to the teaching practice of an operational amplifier for simulating electronic technology courses, can arouse the interest of students inparticipating in teaching, and improves the teaching effect.

Description

technical field [0001] The invention relates to a multi-person voting device used in the teaching of analog electronic technology, which belongs to the field of electronic technology. Background technique [0002] Analog electronic technology is the basis of electronic technology and a basic course for electrical majors. Operational amplifiers are one of the core contents of analog electronic technology courses. At the same time, operational amplifier circuits are often used in power supplies, signal amplification, signal filtering and other occasions. They are widely used. In order to verify the theoretical learning content, teachers usually arrange separate verification experiments , due to the lack of interest in the verification experimental circuit, students are not interested in learning, which affects the teaching effect. Therefore, it is very necessary to design a teaching device that can not only mobilize students' learning enthusiasm but also integrate the content...
