Abstract :
A microwave radio system channelized by pulse amplitude modulation (PAM) has been developed to fulfill a need for a short-haul, low-cost communications link having a moderate traffic capacity. For such short-range operation the microwave equipment has been greatly simplified, eliminating many of the refinements necessary for trunk-line workings. The PAM multiplex terminal subdivides the 100-kc information band into eight 3,000-cycle voice bands, employing a 3-element binary counter as the time division distributor.
