Abstract :
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 θ in the range 0.38π ⩽ |θ| ⩽ 0.44π and 0.56π ⩽ |θ| ⩽ 0.62π and for the radius in the range 0.5 ⩽ r < 1
