随后，本文还简要介绍了信号调理器、保护屏蔽接地与电源、计算机接口、信号处理等。

Then it came the signal debug device, protecting shield and power source, computer connection, signal process.

抑制干扰也从电源系统、地线、信号线等方面采取措施，通过隔离、屏蔽、滤波、接地等方法，在软件上采取数字滤波。

We take measure for inhibition interference by power supply system and signal wire and ground wire etc. Using digital filter in software through isolate, screen, filter and ground connection etc.
