A family of compatible high-density bipolar codes (CHDB), which allow unrestricted binary signaling on pulse-code modulation (PCM) systems, while limiting the number of consecutive 0's in the coded sequence, are presented. CHDB compares favorably to other transmission plans with the same purpose. Examples of coding, decoding, and error monitoring hardware are given.
