Abstract
An error correction circuit employs a digital averaging technique to overcome transition bit errors in a plurality of original binary bits ideally arranged as a thermometer or circular code. The circuit first generates a like plurality of intermediate signals respectively corresponding to the original bits. Each intermediate signal varies according to a weighted analog summation of a specified odd number of consecutive original bits centered about the corresponding bit. The circuit then compares the intermediate signals with corresponding further signals to produce a corrected code.
