| Abstract: | 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. |
