摘要
全部 3 4种待测信号分为 5类 ;开关信号 ,电压信号 ,低频信号 ,高频信号和物理信号 .通过 4种功能电路 ,把这些信号经过隔离并变换成可以被计算机 A/D板直接采样的电压信号 .给出了每种电路的测试数据和结果 .
Thirty-four undertested signals were classified into five groups:switch signals,voltage signals,low frequency signals,high frequency signals and physical signals.Four function circuits were designed to isolate and transmit all of these signals into voltage signals which could be directly sampled via computer A/D interface.Detailed test data for each circuits were presented as well.
