基于增益控制的音调调节电路解析与调试

Analysis and Debugging of tone Adjustment Circuit Based on Gain Control

音调控制电路具有结构简单、易于搭建等特点,通常作为《模拟电子技术》课程的实验、实训项目的一部分。学生制作完成后由于元件性能、焊接、布线、调试等差异,电路性能差别较大。文章从电路定性分析、电路调试、电路测量等方面入手,为学生介绍音调控制电路制作与调试方法,以期望达到较好的电路效果。

The tone control circuit is characterized by its simple structure and easy to set up.It is usually used as part of the experimental and practical training course of the"Analog Electronic Technology".After the circuit is made,because of the differences in component performances,welding,wiring,and debugging,etc.,the circuit performance is different.In this paper,Starting from qualitative analysis,circuit debugging,circuit measurement,introduces the method of making and debugging the tone control circuit,in order to achieve better circuit effect.
