Coupling & Bypass Capacitors
2.0 - Coupling Capacitors. The purpose of a coupling cap is to pass the wanted audio (AC) signal, while blocking any DC from preceding stages or source components. DC will cause pots to become noisy (scratching noises when operate), and cause relatively loud clicks when (if) muting relays or similar are used. Since DC carries no audio ...
Coupling and Decoupling | Applications | Capacitor Guide
The role of coupling capacitors is to prevent the incoming AC signal from interfering with the bias voltage applied to the base of a transistor. In such applications, the signal is driven to the base of a transistor through a serially connected coupling capacitor. The capacitance value must be chosen so as to allow the useful signal, for example voice, to propagate freely, while …

Introduction to Coupling Capacitor
A capacitor which is used to link one circuit''s AC signal to another circuit is referred to as a coupling capacitor. Blocking the DC signal and allowing the AC signal from one circuit to another is the main feature of this capacitor.

Stop Worrying About Coupling Capacitors!
Coupling capacitors in series between stages of an audio circuit generally have a large enough value to roll off starting below 20 Hz. Since little audio voltage is lost across a coupling capacitor at the higher audible frequencies, in theory their distortion should not be a factor. This is exactly what I set out to prove or disprove with my tests. The main contributor to …
