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

I. I. Trifonov, Yu. Yu. Shelepenko, S. Yu. Shelepenko


The paper considers methods and examples of solution to the problem of approximation of AFR of digital recursive LPF with any ratio between the powers of the numerator and denominator of the transfer function polynomials and with a prescribed function of guaranteed attenuation in the rejection band.
