The baseband signals can be many, but before modulation they have to be converted to digital signals. TDMA is therefore uniquely suited for transmission of digital signals such as TDMA-PCM [pulse code modulation] telephony or data signals. TDMA has been used in a number of systems, e. g. signalling and access information channels in the SPADE and MARISAT systems.  6, record 3, English, - time%20division%20multiple%20access
