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
