摘要
本文研究了场效应管构成音量调节电路的新应用,得出了这种新应用的控制特性曲线与控制电压的分布范围,为工程设计提供了依据。据此结果设计的级差音量调节电路,已成功地应用于 AA—800与 AAC—1000型的语言学习系统。
The application of fieldistor as a component in the circuit of volume adjuster is studied in this paper.The first achievement lies in the control characteristic curve and the range of control volt- age.This provides a scientific basis for engineering design.The circuit design of range volume adjuster based on this study has been successfully applied to the AA—800 and AAc—1000 type language learn- ing system.
