Abstract :
Single side-band (ssb) and independent side-band (ISB) radiotelegraph systems allow for a high degree of frequency-division multiplexing as contrasted to the requirement for time division multiplexing in usual frequency shift keyed carrier systems. This advantage is the principal justification for its use, especially for those circuits requiring high-speed traffic-handling capacities.
