Abstract
Pulse-code modulation (PCM) makes possible a transmission system in which the ultimate signal-to-noise ratio at the receiver is independent of the distance spanned, provided that noise peaks at the receiver remain below a sharply-defined threshold value of approximately half the signal strength. The advantages of such a system for long-distance communications are apparent. These advantages must be weighed, however, against the increased bandwidth required for transmission in any particular application.
