❶ DC couple与AC couple的区别

【区别】

AC couple是驱动信号中的直流部分，允许交流部分通过。

DC couple既允许交流部分，又允许直流部分。

【注】AC指的是 “交流电” ，DC指的是“直流电”了 ，经过变压器的 一般都是DC了 而常用的居民用电 都是 220V的 AC 交流电 50Hz

Basic Information about AC and DC Coupling
Hardware: Multifunction DAQ (MIO)

Problem:
What are AC and DC coupling?

Solution:
AC coupling consists of using a
capacitor to filter out the DC signal component from a signal with both
AC and DC components. The capacitor must be in series with the signal.
AC coupling/ is useful because the DC component of a signal acts as a
voltage offset, and removing it from the signal can increase the
resolution of signal measurements. AC coupling is also known as
capacitive coupling.

DC coupling describes any voltage signal acquisition in which both AC and DC components are measured.
