For an RC integrator circuit, the input signal is applied to the resistance with the output taken across the capacitor, then V OUT equals V C.As the capacitor is a frequency dependant element, the …
A Complete Guide to Capacitors
Filter AC noise from DC circuits – any AC signals that may be on a DC bias point, power rail, or other nodes that need to be free of a particular varying signal should be removed by the capacitor. It must also be able to withstand the supply voltage while supplying and absorbing the levels of current arising from the noise on the rail.
