Binary data coding and decoding system - uses transforming circuit reducing distortions due to successive regenerations of digital transmission

摘要

The coding and uncoding system for k binary signals a(n, i) (i = 0, k-1), includes a transformer converting each binary train, a(n, i) into a binary train b(n, i). The binary train b(n, i) is delayed and combined with the incident binary train. The k bits of the word An = (a(n, i)) formed by the k synchronous incident trains are treated simultaneously. The word Bn = (b(n, i)) is formed in which each bit b(n, i) is obtained by being combined with the bits b(n-x, j) and b(n-x', j') such that x and x' are integers less than n.
