Coupling capacitance:

Connected between the signal source and the signal processing circuit or the two stage amplifier, it is used to separate the direct current, let the alternating current or pulsation signal pass through, and make the DC working point of the believed amplifier do not affect each other.

 

Bypass capacitance:

AC or pulse signals in the AC / DC signals are connected to the two ends of the resistor or directly to the common telecommunication from a certain point to avoid the voltage drop when the AC component passes through the resistor.
