The capacitor C 1 and C 3 are commonly known as "coupling capacitors". The coupling capacitance C 1 lets only the alternative current (AC) signal pass as an input of the CEA configuration while blocking the direct current (DC) to go from the supply to the source.
The decoupling capacitor acts as a practical short-circuit to any AC noise voltage, while not affecting DC voltage signals between those two points at all. So long as the decoupling capacitor value is significantly larger than the stray "coupling" capacitance between the cable''s conductors, the AC noise voltage will be held to a minimum.
