SIGNAL TRANSMISSION SYSTEM

摘要

A signal transmission system comprises a transmitter, a receiver and a transmission link in which the signal to be transmitted is pulse code modulated. The transmission link comprises a plurality of channels (0-7), one for each bit of the pulse code modulated signal. The quality of each channel is monitored and the bits of the pulse code modulated signal are applied to the channels such that the most significant bits of the pulse code modulated signal are allocated to the channels having the lowest level of interfering signal.
