Which multiplexing technique transmits each signal from one input source via a single time slot through the creation of different slots?

The correct choice focuses on Synchronous Time Division Multiplexing (STDM), which efficiently allocates bandwidth by dividing time into distinct time slots for each signal from various input sources. Each source is designated a fixed time slot in a recurring cycle, ensuring that data is transmitted in an orderly manner and maximizing the use of the available bandwidth.

In STDM, each input signal is transmitted in its assigned time slot, without overlap, which provides a structured approach to managing multiple signals over a single channel. This method is effective in environments that require consistent and predictable bandwidth allocation, making it suitable for applications where regular data transmission is vital.

In contrast, while options for asynchronous time-division multiplexing involve variable time slots based on demand, STDM employs fixed slots, leading to more predictable performance. Frequency Division Multiplexing deals with splitting the available bandwidth into different frequency channels rather than time slots. Time-division multiplexing is a broader term that may include both synchronous and asynchronous techniques but does not specifically address the fixed slot method that defines STDM. Thus, Synchronous Time Division Multiplexing accurately describes the intended method of transmitting signals in dedicated time slots.
