Abstract :
An inverse filter, incorporating a charge-transfer-device (c.t.d.), tapped analog delay line and digitally programmed tap weights, is reported. This computer controlled analog processor performs a zero-forcing algorithm under software control. The inverse filter (or transversal equaliser) is demonstrated with an LC resonator as the distorting medium. The results show that this processor permits partially overlapping distorted impulses to be clearly discriminated.
