In a sharp cutoff bandpass or bandstop recursive digital filter, the poles and zeros are expected to be clustered around the band edges, and in close proximity of the unit circle in the z-plane.… (More)

In the coefficient translation methods for reducing sensitivity in recursive filters the modified coefficients can be realized with multipliers of shorter wordlength i.e., by fewer number of bits.… (More)

Modulo arithmetic modulo a prime integer have many interesting properties. Such properties are found in standard books on number theory. Some properties are especially of interest to the signal… (More)
