TRANSMITTING CIRCUIT AND RECEIVING CIRCUIT

摘要

PROBLEM TO BE SOLVED: To reduce an effect caused by mark ratio deviation against a higher-speed digital baseband signal when two digital baseband signals having different speeds are transmitted with multiplex modulation. SOLUTION: A lower-speed digital baseband signal is multiplexed with the higher-speed digital baseband signal after being phase-modulated correspondingly to a clock signal regenerated from the higher-speed digital baseband signal.
