Gain of a passive filter
WebUses for passive filters. Filters are widely used to give circuits such as amplifiers, oscillators and power supply circuits the required frequency characteristic. Some examples are given below. They use combinations of R, L and C. As described in Module 6, Inductors and Capacitors react to changes in frequency in opposite ways. WebDec 24, 2024 · Active or Passive Filters. The filters are also divided based on the components used while designing the filters. If the design of the filter is completely based on passive components (like resistor, capacitor & inductor) then the filter is called passive filter. ... Similar to the first-order filter, the gain of the filter will be the same as ...
