Coupling capacitors are used in electronics to link different circuit stages together while isolating the intended DC operating point of each stage so that they are not disturbed by the adjacent connections These capacitors thus separate the quiescent values of each stage from the others while allowing AC signals of interest to 'pass' through, and be processed by, the different stages unperturbed. This question explores the steady-state operations of the coupling capacitors. The circuit below shows the small-signal equivalent model...
