A multi-output second-order digital filter structure for VLSI implementation
暂无分享,去创建一个
A multi-output second-order digital filter structure without zero-input and constant-input oscillations is presented. It could be used for the realization of low-pass, high-pass, band-pass, and band-stop Butterworth, Chebyshev, and elliptic digital filters, and all-pass digital filters. The overall structure consists of two delays, three multipliers, and nine adders, which could be adopted for VLSI implementation.
