The Phase-Frequency Response Influence on the Tunable Frequency-Dependent Component Coefficients

This study deals with the influence of the second order tunable digital frequency-dependent components' transfer function coefficients on the phase-frequency response during those components tuning. The obtained approximations of PFR dependence on the ripple level allowed us to find the digital filter transfer function of the denominator coefficients values that contributes to a more rapid rearrangement of their characteristic responses when built in the platforms with limited computing and energy resources.
