Abstract

Abstract A register translator circuit is disclosed which receives plural order binary data from a time division pulse code modulation system and in response thereto, (1) registers the data in storage flip-flops, (2) checks the data for parity, (3) compares the registered data with that subsequently received on a retransmission of the same information, and (4) if the comparison test passes, translates the registered information into a plurality of 1-out-of-N bits. If either the parity or comparison test fails, the input flip-flops are reset and the above operations are repeated until identical data with good parity is received on two successive transmissions. Each data word is represented by a timewise staggered sequence of signals not all of which are overlapping. Because all signals representing a word do not overlap, a comparison circuit is provided which is divided into a first and a second half each of which is individual to a corresponding portion of the data word received on successive transmissions.
