Most electronic filters are linear. The Butterworth filter has the ‘smoothest’ frequency response in terms of having the most derivatives of its magnitude response being zero at the geometric center of the passband. There are two principal reasons for the use of active filters. function gtag(){dataLayer.push(arguments);} This class of filters approximates the ideal filter well in the pass band. The first is that the amplifier powering the filter can be used to shape the filter's response, e.g., how quickly and how steeply it moves from its passband into its stopband. Filter is basically linear circuit that helps to remove unwanted components such as Noise, Interference and Distortion from the input signal. All rights reserved.
