A DIGITAL FILTER FOR SEPARATING HIGH- AND LOWFREQUENCY COMPONENTS OF A TRANSIET SIGNAL,

Abstract

A filter is described which separates a transient signal into high- and low-frequency portions and introduces no phase shifts or amplitude changes in either portion. A program written in FORTRAN for an IBM 7090 computer which will filter a sampled time-history record is presented. Simple formulas are given for estimating errors in the filter that are due to sampling and truncation of the continuous record. Application of the filter to signals produced by two or more physical sources is discussed. (Author)
