Class Information
Number: 341/63
Name: Coded data generation or conversion > Digital code to digital code converters > To or from bit count codes
Description: Subject matter for converting digital signals to or from other digital signals by counting the number of zeros and or ones in the signal and substituting a digital indication of that count in place of the actual bits (e.g., run length codes).
