摘要
本文介绍将普通示波器加装单片机之后,变为一记忆波器,可以很方便的用来观察L、C电路暂态响应的波形,而普通示波器是难以实现的。本文着重介绍加装单片机的接口电路以及A/D和D/A转换控制程序。
A general oscillograph may be coverted into a rememberable one by adding to it a single chip microcomputer. Rememberable oscillograph can be used to watch the waveform of a transient respondence of a L and C circuit conveniently. This paper deals mainly with the interfacing circuit of single chip microcomputer, and the control piogram of conversion from A/D to D/A.
