What Is A Filter Circuit
A filter circuit is generally a combination of inductors (L) and capacitors (C).The filtering action of L and C depends upon the basic electrical principles. A capacitor C passes a.c. readily but does not pass d.c. at all. On the other hand, an inductor L opposes a.c. but allows d.c. to pass through it.
