Coupling Capacitors 5/15/2001 Ken Parker 1 of 2 Coupling Capacitors 1 AC Coupling AC Coupled signals1 pass through a classic RC high-pass filter as shown in Figure 1. Some amount of signal degradation also occurs, as shown. The time constant of the RC filter determines the amount of ''decay'' in the signal.

Learn MoreThis has the effect of altering the circuit dc load line and Q-point. The use of an output coupling capacitor (C 2) is illustrated in Fig. 6-2(c).Like the input coupling capacitor, C 2 offers a dc open circuit and behaves as an ac short-circuit. Thus, it passes the output waveform to the load without affecting the circuit bias conditions.
