本文介绍矩阵方式和开关方式的立体声编码与解码电路。重点讨论开关方式,从如何取得优良分离度指标的角度出发,对“硬”开关方式、数字合成法和“软”开关方式编码器与双平衡乘法开关解码器和锁相立体声解码器进行了理论分析和电路介绍。
This article describes the matrix mode and switch stereo encoding and decoding circuit. This paper focuses on the switch mode. From the perspective of how to obtain the excellent resolution index, the theory of “hard” switch mode, digital synthesis method and “soft” switch mode encoder and double balanced multiplication switch decoder and phase locked stereo decoder Analysis and circuit introduction.
