Multiplexing multiple broad and narrow band digital signals - combining signals in one stage and combining resultants in second

摘要

Each of a number of multiplexers of a first stage forms, from a broad-band signal and a number of narrow band signals, a first multiplex signal. A second stage multiplexes has a number of inputs, to each of which is coupled an output of one of the first multiplexers. It forms, from these inputs, a second stage output multiplex signal. USE/ADVANTAGE - Supplying multiple radio and television signals to dwelling area. Each signal is in digital form, and number of digital narrow-band signals in integer multiple of multiple number of digital broadband signals.
