What is a filter in a circuit?

What is a Filter? If your filter consists of nothing more than resistors, capacitors, and inductors, you have a passive filter. The circuit becomes “active” when you incorporate an active component, e.g., a transistor.

What are the components of a filter circuit?

A filter circuit consists of passive circuit elements i.e., inductors, capacitors, resistors, and their combination. The filter action depends upon the electrical properties of passive circuit elements. For example, an inductor allows the D.C. to pass through it. But it blocks A.C.
