What is Filter? A filter is a frequency-selective circuit. Filters are designed to pass some frequencies and reject others. The series and parallel resonant circuits reviewed in Section 2-2 are examples of filters. There are numerous ways to implement filter circuits. Simple filters created by using resistors and capacitors or inductors and capacitors are called … Read more

What is Filter Circuits ? Generally, a rectifier is required to produce pure d.c. supply for using at various places in the electronic circuits. However, the output of a rectifier has pulsating *character i.e. it contains a.c. and d.c. components. The a.c. component is undesirable and must be kept away from the load. To do … Read more
