Capacitive coupling (CC) is the counterpart to IC, as it is based in the electric field coupling between two conductors that form the forward and reverse current paths. WPT across the tissue layer occurs when a second pair of conductors that form the RX part of the system are placed close to the TX pair.

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.

The coupling capacitor is our solution. As you know, capacitors block DC and allow AC. The capacitance value can be small. We simply want to block the DC and allow all audio frequencies to pass. In our case, we will use 0.22uF as a commonly used and available
I wonder what the purpose of the coupling capacitors and the bypass capacitors are and the type of effect each capacitor has on the circuit. As I''ve understood it, you use coupling capacitors to block DC and avoid interference (what does that really mean?) and the bypass capacitor is to have a short-circuit in the emitter of the transistor (and what does this really …
