The principle of a simple two-channel TDM system is illustrated in Fig. 39.18. Analog inputs are considered for clarity. TDM is, of course, normally a means of multiplexing digital signals, such as PCM pulses, all having the same amplitude.
Fig. 39.18 A simple two-channel TDM system: t1 = a series of pulses occurring at fixed intervals; t2 = a series of pulses occurring at the same periodicity as t1 but commencing later by an amount equal to half the time interval
The two channels, which are to share the common circuit, are each connected to it via a channel gate. The channel gates are electronic switches which permit ...
