ABSTRACT:
A system for communicating binary data by minimum shift keying wherein specified relationships maintained by a transmitter between the bit rate of the binary data, the frequency of a mark signal and the frequency of a space signal allow derivation in a receiver of coherent reference signals for both mark frequency and space frequency by a single phase lock loop. Provisions are also made for similar derivation of a coherent reference for a carrier frequency.
