Abstract

PURPOSE: To ensure the optimum reception for the signal featuring a large transmission distortion through switching of more than one unit of the equalizer.
CONSTITUTION: The signal sent from transmission circuit 1 receives distortion at transmission line 2 and then supplied to receiver circuit 5 via equalizer 4a. When some error is detected (6) in the signal at circuit 5, change-over swicth 3 is actuated by the detection output. And then the reception is carried out again by switching the equalizers. As each equalizer features different correcting performance, the optimum reception is possible though either one of the equalizers
