Sensitivity properties of all-pole canonical low-pass G/sub m/-C filters

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 canonical structures up to 10-th order ones is performed for Butterworth filters. Design guidelines that follow from the presented results are also given.
