RC Circuit


The RC circuit, or resistor–capacitor circuit,RC filter, RC network, is a circuit composed of a resistor and a capacitor, and widely used in analog circuits and pulse digital circuits. According to the connection method of the capacitor resistance, RC circuit can be divided into RC series circuit and RC parallel circuit.

For the RC parallel circuit, it can attenuate the effect of the low frequency signal if it is connected in series in the circuit, and if it is connected in parallel, the RC parallel circuit can attenuate the effect of the high frequency signal (that is, the filtering function).
