Abstract


A computation program, written in FORTRAN IV
language, for numerical filtering of time series is described. It was tested
with an IBM 7094/7040 DCS computer.
The numerical filtering operation allows to extract or suppress in a
time series prefixed frequency waves indipendently by the change of phases
and wideness with which they can appear
