电视接收机双通道伴音数字信号处理方法

The Digital Signal Processing Method for a Two-channel Television Sound in Television Receiver

本文叙述了全部使用数字信号处理方法完成的一种双通道电视伴音译码器。这种译码器使用内插Ａ／Ｄ和Ｄ／Ａ转换方法可在ＩＣ处理中实现这些功能，这些处理与译码器的数字部分兼容。数字双通道电视伴音系统改进了模拟双通道电视伴音系统的性能。文中对该系统的数字信号处理方案作了一些探讨。

This Paper describes a two-channel television sound decoder which is completly useddigital signal processing method.This decoder is employed interpolation A/D and D/A can-version method that can be realized in IC processing,and these processing are compatiblewith the part of digital in decoder. The system for digitai two-channel television sound hasimproved the property of the system for analogue two-channel television sound. The schemeused digital signal processing for this system is explored in this paper。
