| 摘 要： | In recursive digital filter design,the amplitude characteristic of an ideal filterhas to be translated into a rational function that is pole-free on the closed unitdisk and preferably has real coefficients.This is possible through a causal trans-formation utilizing the tolerance allowance.In this paper we study the degree ofuniform approximation by rational functions. |
