Filters are then classified in the standard formats namely as lowpass, highpass, bandpass or band-reject according to their frequency resp

It is shown that the corresponding gain function (magnitude response) involves a polynomial, the approximating polynomial, which defines the approximation and determines its characteristics. For the classical Butterworth,

These approximations share the common attribute of having finite zeros on the .-axis thereby making the gain equal to zero at these positions in the stopband. These transmission zeros force the gain response to exhibit stopband ripple. As in

The usual mathematical treatment of such filters involves elliptic functions which are considered as a “difficult” area. However, we show that elliptic functions are as straightforwar

In the general case presented in earlier chapters, we have determined for each approximation the corresponding transfer function of the filter from given magnitude specifications. Although this can be done in the case of passive filters, it is preferable to determine the input imp
