Abstract

Errors in a predetermined digital sequence are detected by utilizing a detector which includes memory elements such as a series shift register, and logic gates for detecting a predetermined subsequence. Errors are detected by comparing each bit in the data stream with the output of the memory. Logic gates inhibit the detection of an error in response to the subsequence detection.
