In data transmission, what is a characteristic of Time Division Multiplexing?

• A. Signals occupy the channel simultaneously
• B. Signals are interleaved over time
• C. Signals are combined based on frequency
• D. Signals are encrypted before transmission

Answer: (B)

Time Division Multiplexing (TDM) is a technique used to transmit multiple signals over a single communication channel. In TDM, each signal is allocated a specific time slot during which it can transmit its data. This means that multiple signals do not occupy the channel simultaneously; instead, they are interleaved in time, with each signal utilizing the channel in its designated time interval. This interleaving allows for efficient utilization of the channel because it ensures that signals are sent in a defined order over specific time periods, without overlap. By dividing the time into slots, TDM can effectively manage the transmission of various signals, ensuring that each sender has the opportunity to transmit its signal without interference from others. This method contrasts with frequency division multiplexing, where signals are separated by different frequency bands, and it does not involve encryption processes unless explicitly stated as part of a communication protocol. TDM is widely used in digital communications, including telephone networks and data transmission systems.
