AC coupling is common in amplifier circuits for practical and historical reasons. The practical reason is to remove DC power on a transmission line and into a load. The historical reason is to conform ...
Communication systems often require large ac output coupling to remove dc voltage on the transmission line and to isolate ground connections between transmit and receive systems. Generally, a feedback ...
A capacitor measured with a $100 handheld multi-meter can give a substantially different result than the same capacitor measured with a $10,000 LCR meter. That same capacitor measured with two ...
