Low sensitivity second-order bandpass digital filter structure
Gordana Jovanović Doleček, Sanjit K. Mitra · Electronics Letters · 2002
A new low sensitivity second-order bandpass digital filter structure is presented. The proposed structure has the smallest absolute angle sensitivity and a moderate radius sensitivity for the pole angle thetas in the range 0.38π≤|thetas|≤0.44π and 0.56π≤|thetas|≤0.62π and for the radius r in the range 0.5≤r<1.
