Serial multi-gigabit data channels usually have capacitors connected in series in micro-strip lines (AC coupling capacitors) to pass through the high-frequency signals content and to allow different DC supply for a driver and receiver at the same time Mounting structures of such capacitor and capacitors themselves are
Coupling Capacitor Calculation. The capacitance of the coupling capacitor can be calculated similarly to that of the basic capacitor. Capacitance is measured in terms of the unit known as Farads. But the farad is the largest unit so it is divided into sub-units of picofarads, micro farads, and nano farads.

In analog circuits, a coupling capacitor is used to connect two circuits such that only the AC signal from the first circuit can pass through to the next while DC is blocked. This technique helps to isolate the DC bias settings of the two coupled circuits. Capacitive coupling is also known as AC coupling and the capacitor used for the purpose is also known as a DC-blocking capacitor. A coupling capacitor''s ability to prevent a DC load from interfering with an AC source is particula…

The biggest disadvantage of AC coupling is that the capacitor really will block DC, as it''s meant to. If the signal you want to transmit makes important use of specific DC voltages, the coupling capacitor will not pass those voltages through.

As mentioned, capacitors will block DC while allowing AC to flow through them. The signal from a guitar is AC, while the current in the actual pedal is DC; if these mix there can be interference and noise in the pedal, which is obviously bad.
