❶ DC couple與AC couple的區別

【區別】

AC couple是驅動信號中的直流部分，允許交流部分通過。

DC couple既允許交流部分，又允許直流部分。

【注】AC指的是 「交流電」 ，DC指的是「直流電」了 ，經過變壓器的 一般都是DC了 而常用的居民用電 都是 220V的 AC 交流電 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.

生意應該不錯的，合肥這邊的電子元器件不少都是從外地發貨過來的
