Approximation of amplitude-frequency responses of minimum-phase recursive digital band-pass filters

I. I. Trifonov, K. S. Skiba

Abstract


The paper considers a method of treatment and an example to the problem of approximation of AFR of digital recursive band-pass filters with any ratio between powers of the numerator and denominator of the transfer function polynomials and for a prescribed function of guaranteed attenuation in the rejection band.
