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. On the other hand, if we use an active component...

AButterworth filteris a type of signal processing filter designed to have a frequency response as flat as possible in thepassband. Hence the Butterworth filter is also known as “maximally flat magnitude filter”. It was invented in 1930 by the British engineer and physicist Stephen Butterworth in...
