Coupling capacitors (or dc blocking capacitors) are use to decouple ac and dc signals so as not to disturb the quiescent point of the circuit when ac signals are injected at the input. Bypass capacitors are used to force signal currents around elements by +- 30 k ...
Capacitive coupling
Capacitive coupling decreases the low frequency gain of a system containing capacitively coupled units. Each coupling capacitor along with the input electrical impedance of the next stage forms a high-pass filter and the sequence of filters results in a cumulative filter with a cutoff frequency that may be higher than those of each individual filter.

Decoupling Capacitor vs Bypass Capacitor – Working
In this article we will learn about these two capacitors types, how they function in a design and how to select a capacitor that is to be used as a bypass capacitor or decoupling capacitor. While the terms Bypass capacitors and Decoupling capacitor are used interchangeably, they have their own differences.
Capacitor Voltage Transformer (CVT Or CCVT)
Coupling Capacitors are only used for coupling high-frequency communication signals and they are equivalent to the capacitive part of CVT. Series connected capacitor elements, housed in porcelain shells, each hermetically (in an airtight manner) sealed, are referred to as capacitor sections.
