Abstract

PURPOSE:To correct automatically correct distortion generated on a transmission line at a reception side, by composing the device of a method which sums products between delay outputs and sampled values. CONSTITUTION:Shift register 2 has past reception signal (r) stored in i-th stage 2-i. Memory 3, on the other hand, has impulse signal (h) stored in i-th stage 3-i. Multiplier 4 outputs the product between values (r) and (h) of 2-i and 3-i. Further, adder 5 outputs the sum of outputs of the multiplier to terminal 6. Then, the signal of terminal 6 realizes convolutional integration approximately and reception signals (r) and (t) can be obtained here which have been corrected.
