AC Coupling

A circuit for removing the constant DC voltage from an input signal so that just the AC portion can be processed.

 

Input Signal

+10V - +2V sine signal, with a +6V Dc offset. Making the dynamic signal all positive.

DC Coupled Input

Same as input.

AC Couppled Input

Input AC coupled, the pffset (Dc component) is removed, the signal is now centered about 0V.
