Passive Filters . Filter circuit which consists of passive components such as Resistors, Capacitors and Inductors is called as Passive Filter. The operating frequency range of the filter banks on the components used to build the circuit. Hence the filter can be further categorized based on the operating frequency of a particular circuit. They are:
