摘要
本文讨论了34Mb/s彩色电视系统中亮、色分离差分编码器。按照整个系统的要求,亮度信号选用6.75MHz取样频率,色差信号选用3.375MHz频率。文中介绍了差分编码器的设计方法及电路实现中的一些具体问题。
The paper discusses DPCM encoder for 34Mb/s color digital television system. According to the requirement of whole system, the sampling fregnency of Y signal is selected as 6.75MHz, and that of C signal as 3.375MHz. Design of DPCM encoder is described, and some practical problems in the implementation of circuit are discussed.
