Transitional Butterworth-Thiran recursive digital filters
Negovan Stamenković, Vidosav Stojanović · 2012
The transitional Butterworth-Thiran recursive digital filters (TBTh) whose characteristics change gradually from the characteristic Butterworth filter to the characteristic Thiran filter which have maximally flat group delay characteristic is present in this paper. The poles of the transition filter are obtained by interpolation between the poles of the Butterworth filter and poles of the Thiran filter.
