Donald G. Albert · US Army Corps of Engineers: Engineer Research and Development Center (Knowledge Core) · 1986
This report describes and gives user instructions for a series of FORTRAN subroutines that can be used to design and apply zero-phase freqeuncy filters to digitized data. The general properties of these filters are discussed and complete listings are presented. Keywords include: Bandpass filters; Bandstop filters; Digital filters; FORTRAN; High pass filters; and Low pass filters.
