Summary:An error correction circuit employs a digital averaging technique to overcome transition bit errors in a plurality of original binary bits (D1-DM) ideally arranged as a thermometer or circular code. The circuit first generates a like plurality of intermediate signals (E1-EM) respectively corresponding to the original bits. Each intermediate signal varies according to a weighted analog summation of a specified odd number of consecutive origianl bits centered about the corresponding bit. The circuit then compares the intermediate signals with corresponding further signals (F1-FM) to produce a corrected code (B1-BM).
