Filter circuits

A filter circuit is in general a combination of inductor (L) and Capacitor (C) called an LC filter circuit. A capacitor allows A.C only and an inductor allows D.C only to pass. So a suitable L and C network can effectively filter out the A.C

Filter capacitor | Applications | Capacitor Guide

Filter capacitors. Capacitors are reactive elements, which make them suitable for use in analog electronic filters. The reason for this is that the impedance of a capacitor is a function of frequency, as explained in the article about impedance and reactance.This means that the effect of a capacitor on a signal is frequency-dependent, a property that is extensively used in filter

Electronics Principles and Devices Rectifier with Filter

In the simple shunt capacitor filter circuit explained previously, we have concluded that the capacitor will reduce the ripple voltage, but causes the diode current to increase. This large current may damage the diode and will further cause heating problem and decrease the efficiency of the filter. On the other hand, a simple series inductor reduces both the peak and effective
