A clock recovery circuit detects a zero crossing of the transmitted signal which occurs every one-half period of the lowest frequency transmitted signal. A data recovery circuit detects the presence or absence of a zero crossing during a window portion of each one-half period of the lowest frequency transmitted signal.
