摘　　要：以CPLD为核心器件实现了符合我国高清数字电视视频信号接口参数标准的HDTV图像测试信号发生器的设计,对系统基本原理、CPLD内部逻辑功能设计和硬件构成进行了详细介绍。系统采用MAX+PLUS II软件进行编译、仿真,性能稳定。采用CPLD简化了电路的设计,易于功能扩展。A image test signal generator about HDTV is designed based on CPLD, which accords with the parameter standard of video signal interface about national high definition television. The basic principle of this system, the design of logic function in CPLD and the hardware configuration of this system are all explained in detail. The program is compiled and simulated by MAX＋PLUS II application and the performance of the system is steady. The using of CPLD predigests circuit design and makes it easy to expand functions.
