Abstract

The invention relates to a multi-person voter device for differential amplification circuit teaching, and belongs to the technical field of electronics. The differential amplification circuit is widely applied, which is one of important teaching contents of an analog electronic technology; the objective of the invention is to improve the teaching effect of differential amplification circuit content, a multi-person voter device composed of judge switches K1 to K8, resistors R1 to R14, a consent people number adjusting potentiometer RV1, field-effect tubes Q1 to Q2, a triode Q3 and a result indicating lamp D1 is designed, the multi-person voter device is composed of the judge switches K1 to K8, the resistors R1 to R14, the consent people number adjusting potentiometer RV1 and the field-effect tubes Q1 to Q2. The voter device can adjust different consent people according to requirements, can be configured into the multi-person voter with 1-8 persons, is applied to the teaching practice ofa differential amplification circuit of an analog electronic technology course, can arouse the interest of students in participating in teaching, and improves the teaching effect.

Description

technical field [0001] The invention relates to a multi-person voting device used for differential amplifier circuit teaching, which belongs to the field of electronic technology. Background technique [0002] Differential amplifier circuit is one of the core contents of analog electronic technology. At the same time, differential amplifier circuit is often used in voltage source, current source, signal processing and other occasions. 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 of differential amplification into it. Among them, it can increase the interactivity and interest of the experiment, making the original boring verification experiment more lively and interesting, stimulating students to think deeply about th...
