Sensitivity comparison of high-order all-pole G/sub m/-C filters in canonical structures

In the paper, sensitivity properties of all-pole canonical low-pass G/sub m/-C filters are investigated. We present a general structure of all-pole canonical low-pass filter of arbitrary order as well as its matrix description. The formulas for sensitivity functions are also given. The comparison of sensitivity properties for Chebyshev and Bessel filters is performed. Design guidelines that follow from the presented results are also discussed.
