Coupling Circuits and Techniques using Capacitive, Transformer
With capacitive coupling, two stages are connected using a coupling capacitor,Cc in the diagram. Using this method, the bias levels on the first stage, F1 are isolated from the next stage. Here resistor Rb would be used to bias this stage. The capacitor Cc and Rb and the input impedance at Q1 form a high pass filter, allowing AC current to pass

What is Capacitive Coupling?
Capacitive coupling is referred to in electronics as the transfer of a common energy to different devices linked together through an electrical network. The transfer of energy is done by using different capacitors between circuits. It may also be done in sequence to the original power signal that is intended for coupling.

What is a coupling capacitor?
A coupling capacitor is a capacitor which is used to couple or link together only the AC signal from one circuit element to another. The capacitor blocks the DC signal from entering the second element and, thus, only passes the AC signal.
What is the difference between a coupling capacitor and a decoupling capacitor?
While coupling capacitors pass through AC signals to output, do pretty much the opposite; decoupling capacitors shunt AC signals to ground and passes through the DC signal in a circuit. Decoupling capacitors are designed to purify DC signals of AC noise.
How does a coupling capacitor work in a digital circuit?
The coupling capacitor connecting the two circuits and only allows the AC to pass from one circuit to the other while blocking and isolating the DC bias voltage from moving to the next circuit. In the digital circuits, the capacitive coupling is used to transmit the DC-balanced signal, which is the zero DC component of the digital signal.
Can a coupling capacitor transmit AC signals?
In essence, they can achieve selective transmission of signals. Specifically, coupling capacitors can accurately transmit AC signals from one part of the circuit to another, which is like building a bridge exclusively for AC signals in the circuit.
What is capacitive coupling?
This coupling can have an intentional or accidental effect. Capacitive coupling from high-voltage power lines can light a lamp continuously at low intensity. In its simplest implementation, capacitive coupling is achieved by placing a capacitor between two nodes.
What is the difference between DC power and coupling capacitor?
For example, a coupling capacitor normally is used in an audio circuits, such as a microphone circuit. DC power is used to give power to parts of the circuit, such as the microphone, which needs DC power to operate. So DC signals must be present in the circuit for powering purposes.
