摘要
介绍一种能对各种不同的标准信号、非标准信号进行采集的通用电路。采用一种很新颖的设计方法,在不改变硬件情况下,使用软件进行简单的设定,通过单片机完成对光继电器的控制及数字电位器的调节从而实现对不同信号的采集。
Describes a general circuit used to sample for all kind of different standard and non-standard signals. A new type design method is used, it does not change hardware and only carries out simple setting-up by software, could finish control light microrelay and adjust digital potentiometer through SCM, and different signal could be sampled.
