Rational Approximations,y 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 case of polynomial approximations of the previous Chapter, all necessary design equations are given and the optimal use of the rational approximations is explained in detail.

Frequency Transformations,this Chapter that in order to design a highpass, bandpass or band-reject filter, we can first design an auxiliary normalized lowpass filter which can then be transformed to the desirable filter type. The corresponding frequency transformations are presented and their use is demonstrated in several design examples.

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
