This technique helps to isolate the DC bias settings of the two coupled circuits. Capacitive coupling is also known as AC coupling and the capacitor used for the purpose is also known as a DC-blocking capacitor. Coupling capacitors are typically in series with the signal. Both types are typically common non-polarity-specific ceramic …
