What is digital time division multiplexing?
- A.Two or more data streams are assigned to discrete sub-carriers on an FM transmitter
- B.Two or more signals are arranged to share discrete time slots of a data transmission (correct answer)
- C.Two or more data streams share the same channel by transmitting time of transmission as the sub- carrier
- D.Two or more signals are quadrature modulated to increase bandwidth efficiency
WhyDigital time division multiplexing arranges two or more signals to share discrete time slots of a data transmission. Digital time division multiplexing arranges two or more signals to share a single channel by taking turns in discrete, scheduled time slots, each signal getting its own brief window of the shared transmission, answer B. It isn't assigning separate frequency subcarriers (that's frequency division multiplexing), isn't transmitting time-of-transmission itself as a subcarrier, and isn't a quadrature modulation technique, those describe different multiplexing approaches.
