本文提出了一种实现具有任意幅值特性的零相移滤波器的两通递归方案。第一遍在正向时间执行,第二遍在反向时间执行。初始和反向时间瞬变的影响进行了讨论,并提出了准在线自适应方案。
A two-pass recursive scheme is proposed for realizing zero phase shift filters with arbitrary magnitude characteristics. The first pass is performed in forward time and the second in reverse time. The effect of initial and reverse time transients is discussed, and a scheme for quasi on-line adaptation is presented.
