ABSTRACT:
In a transversal filter equalizer, such as one using a tapped delay line, the present invention combines the symmetrically located pairs of tap signals, by means of adders and subtracters, to provide partial output signals which are separately controlled in amplitude and phase. These partial output signals, which have no d.c. components, are then summed with a partial signal derived from the center tap reference signal to reinsert the d.c. component and to provide the equalized output signal.
