Use of a programmable filter for inverse filtering
D. Behar, H. Olaisen, Gordon S. Kino, Doug Corl, P.M. Grant · Electronics Letters · 1980
A real-time deconvolution or inverse filter, operating at signal frequencies up to 5 MHz, is reported. The programmable digital filter is controlled by a computer which calculates the Wiener-filter solution using f.f.t. techniques. Deconvolved signals can be clearly discriminated after passing through a distorting medium.
