Two different things. Coupling caps you disconnect the low voltage side and measure DC to ground. It will try to fool you, though, because initially the cap will show a bit of DC (caps do this) and then settle down. You need a good meter. Something with Fluke in ...
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.
The characteristics of a capacitor vary mainly depending on the dielectric material used. The dielectric material determines the capacitance value, energy efficiency, and size of a capacitor. Fixed value capacitors can be broadly categorized into two: polar and non-polar capacitors. Non-polar capacitors include ceramic, film, and paper capacitors.

With DC coupling, the oscilloscope properly indicates the shape of the square wave coming from the signal generator. Low frequency: With AC coupling, the high-pass filtering of the coupling capacitor distorts the square wave''s shape so that what is seen is not an accurate representation of the real signal. Direct Coupling
Another method to isolate the speaker from DC bias in the output signal is to alter the circuit a bit and use a coupling capacitor in a manner similar to coupling the input signal (Figure below) to the amplifier. Capacitor coupling isolates DC …
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 other places, you''ll see similar capacitors—though often much smaller—acting as "bright caps", where they''re not asked to block any DC voltage, but simply to pass a certain high-frequency portion of the signal along to the next stage for voicing purposes.
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 …

What is a decoupling capacitor? A decoupling capacitor acts as a local electrical energy reservoir. Capacitors, like batteries, need time to charge and discharge. When used as decoupling capacitors, they oppose quick changes of voltage. If the input voltage suddenly drops, the capacitor provides the energy to keep the voltage stable.

To provide the reduced level tap voltage there are many more C1 capacitor elements than C2 capacitor elements. The capacitor elements are housed
