Transitional Murromaf–Murroer filters
Vidosav Stojanović, Vlastimir Dragoljub Pavlović · Electronics Letters · 1979
A new class of lowpass filters with all transmission zeros at infinity, having equal-ripple behaviour in the passband, is described. The transfer function of these filters, referred to as transitional Murromaf-Murroer filters, is obtained by adding the multiple real poles and reducing the number of complex pole pairs to realise a lowpass RC active filter with a reduced number of amplifiers with respect to the classical transitional Butterworth-Cheby̅shev filters.
