PCM遥测信号源的设计与实现

给出一种基于 EPROM的遥测模拟信号源的设计方案及其实现方法。通过计数器传送地址信号 ,读取烧制在 EPROM里的动态信号码并与计数器本身产生的固定码相结合 ,从而形成多路串行的遥测模拟信号源。该信号源可用于产生各种格式的遥测帧结构 ;可用它对地面视频设备进行调试和性能检测 ;可作遥测专业实践教学的模拟信号源 ,以便了解遥测帧结构。因此 ,它可作为地面遥测站的模拟信号源 ,也可作为其它实验板的输入信号源。格式多样 ,使用方便。

Design and Realization of PCM Telemetry Signal Source

This paper describes the design and realization of P CM telemetre signal source based on EPROM.Through getting dynamic code using the address signals transmitted by the counter and combinating that with the fixed code generated by the counter,the multiplex and serial telemetry signal source i s formed.This signal source can not only be used to generate all kinds of forms and to debug and detect the video ground equipments,but also be used for pract i cal teaching.So it is used as the analogous signal source and the inputting sign al of experimental boards.
