Webmagnitude. The classical digital Butterworth filter and the well-known maximally flat FIR filter [3], [5], [6], [20], [23] are both special cases of the filters produced by the formulas given in this paper. Several authors have addressed the design and the advantages of IIR filters with an unequal number of (nontrivial) poles and zeros. WebFrom Table 8.3, we pick the lowpass prototype with the order of 1 to produce the bandpass filter with the order of 2, as. and applying the lowpass-to-bandpass transformation, it follows that. Hence we apply the BLT to yield. Via algebra work, we obtain the digital filter as. MATLAB Program 8.7 is given for this example, and the corresponding ...
