time division multiplex การใช้

• The downlink consists of a time division multiplex ( TDM ) carrier bursts directed in a hoping fashion to different downlink beams each downlink frame timeslot.
• A wide-band data link from the gateway to the user terminal employs an Orthogonal Frequency Division Multiplexing ( OFDM ) with a Time Division Multiplex ( TDM ) overlay.
• The data is sent in two channels labelled A and B, or four channels labeled A, B, C and D . Data from the different channels are interleaved using a time division multiplex system.
• One of the JERC's first decisions was to build an electronic exchange using the " Switched Highways " system, which employed time division multiplex techniques ( TDM ), while at the same time continuing research on alternative solutions to the problem of electronic switching.
• Whilst the case has been made for clocking in the ADC environment, where it removes one source of error, namely the ratio between the impulse duration and the summing interval, it is deeply unclear what useful purpose clocking serves in a single channel transmission environment since it is a source of both noise and complexity but it is conceivable that it would be useful in a TDM ( time division multiplex ) environment.
