TRANSMITTER SYSTEM OF DATA SIGNAL

摘要

The system improves the data transmission efficiency of two wire data communication by combining the modulated data signal transmission method and the baseband signal transmission method in full duplicate data signal transmission system transmitting the data signal bidirectionally. The system comprises a baseband signal transmission and modulated wave receiving circuit, and a modulated wave transmission and baseband signal receiving circuit. The modulated wave is transmitted/received with the band at which the baseband signal frequency band and the frequency spectrum are separated enough not to interfere with each other.
