A Butterworth filter meeting these specifications is de- termined. Section 6.5, The Class of Butterworth Frequency-Selective Filters, pages 422-. The term Butterworth refers to a type of filter response, not a type of filter. It is sometimes called the Maximally Flat approximation, because for a response order Low-pass Butterworth filter with unity cut-off. • Design steps in obtaining the transfer function of the filter to meet the specifications. For all-pole filters, the Chebyshev filter gives the best amplitude discrimination, followed by the Butterworth and then the Bessel. Page 24.

The cutoff frequency (Fc) is the frequency at which the filter response leaves the error band (or the −3 Obtain transfer function by substituting s by,. Finally,. Problem 3 Design an analog Butterworth filter that has a -2DB pass band attenuation at a frequency ofExperiment / Circuit Simulation. 0 Butterworth Filters. Objectives. 1. To use basic filter circuits to design multi-order filter response.
