Filter Circuit Component. As an inductor allows dc and blocks ac a filter called series inductor filter can be. Passive filters include only passive components resistors capacitors and inductors.
Each of these parts contributes to removing the remaining ac pulses but in different ways. In contrast active filters use active components such as op amps in addition to resistors and capacitors but not inductors. Filters can be placed in one of two categories.
Each of these parts contributes to removing the remaining ac pulses but in different ways.
An analogfilter uses analog electronic circuits made up from components such as resistors capacitors and op amps to produce the required filtering effect. As the name suggests a capacitor is used as the filter and this high value capacitor is shunted. Filter circuits series inductor filter. Passive filters include only passive components resistors capacitors and inductors.
