ANALYSIS OF FREQUENCY-RESPONSE SENSITIVITY OF THE SECOND-ORDER SECTIONS WITH A REDUNDANT NUMBER OF MULTIPLIERS OF RECURSIVE DIGITAL FILTERS

摘要

The paper considers the possibilities for diminishing the sensitivity of frequency responses to variation of components' parameters and the mean-square sensitivity of frequency responses of minimum-phase and nonminimum-phase sections with an excessive number of components. These sections are used for the realization of transfer functions of recursive digital filters obtained at the approximation stage of design.
