Abstract
An equalizer comprises a tapped delay line of a transversal filter and first equalizing means responsive to a short pseudo-noise train supplied thereto for adjusting tap gains so as to make the transversal filter output signals simulate a pseudo-noise train generated at the receiver with the pulse pattern of the supplied pseudo-noise train. Larger ones, in absolute values, of the adjusted gains are placed at the center of the delay line. Responsive to a subsequently supplied long pseudo-noise train, second equalizing means self-adaptively adjusts all tap gains. The delay line preferably comprises delay units, each for a half of a common clock interval of the supplied pseudo-noise trains and data signals.
