Capacitors Guide: Types, Uses and Choosing the Right One
Coupling – capacitors block DC signals and allow AC signals to pass through, and as such they can be used to couple one section of a circuit with another. Often used in loudspeaker applications. Decoupling – capacitors can block out unwanted noise and voltage spikes, stabilising the voltage supply to integrated circuits.
What is Coupling Capacitor, Construction, Working & Applications
DC Blocking: Since capacitors block DC after the initial charging phase, any DC offset or component present in the input signal is blocked, allowing only the AC component to pass through to the next stage of the circuit. Use of Coupling Capacitors: Coupling Capacitor Working How to Choose the Value of the Coupling Capacitor:

Coupling & Bypass Capacitors
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.

PCIe AC coupling capacitor size
The Design Guide specifies that the AC coupling capacitors for all PCIe interfaces should have a value of 0.22uF, but I noticed that the P3768 reference design uses 0.1uF capacitors for the PCIe#1 interface (M.2 WIFI/BT). Is that a mistake in the design, or do certain devices need to use 0.1uF capacitors? Should 0.22uF be used on all the PCIe …

AC Coupling Capacitor Selection for Wolfson AFE devices
across the ac coupling capacitor is very significant in terms of maximising the dc input range. Increasing CC, for example, to 330pF would increase VSAMPLE = 0.485Vp-p and so increase the input range. SUMMARY This application note explains the importance of careful choice of ac coupling capacitors between imaging sensors and Wolfson AFE devices.
