摘要
本文介绍了一种专用的小型数传接收机，适用于接收从远处发送的测试数据码（ＦＫＳ或ＡＦＫＳ），经解调还原后送人ＣＰＵ或基站微机处理，从而实现远距离测控．叙述了一些电路设计要前及性能测试．其结果令人满意．
A special radio data receiver for measurement and control is described in this paper.The testing FSK or AFSK data from far away are received,demodulated and fed into the CPU in base station for data-processing,thus the remote measurement and control are realized. Several key pointsabout the design of electric circuis are given. It has been proved that theperformances of the receiyer are very satisfied.
