Method and apparatus for rapid initial setting in synchronous data transmission systems of transversal equalizer tap coefficients employ a resistive matrix between all delay-line taps and each attenuator to make attenuator input signals mutually orthogonal. The values of the resistive matrix elements are predetermined in accordance with the amplitude characteristics of the distorting transmission medium and the type of signal processing employed. The effect is to reduce the settling or convergence time for initial equalizer adjustment to two or three signaling intervals even in partial-response signaling systems.
