| 内容記述 | This paper proposes a new discrete optimization method which is mainly directed toward saving computing time for high-order FIR filters. A transfer functions first approximated in a cascade form of a low-order function W(z) with pre-rounded coefficients and a high-order function F(z) with infinite precision coefficients. Rounded F(z) coefficients are discretely optimized to minimize the mean square error of the amplitude response. The roundoff error spectrum is shaped to be suppressed by a weighting function W(z). In order to save computing time, the error is equivalently evaluated in a time domain, and the F(z) coefficients are divided into small groups in the discrete optimization procedure. Design examples for 200 tap FIR filters demonstrate practical usefulness. | |||||
