Which process involves sending multiple signals over a common channel using successive time intervals?

• A. Frequency Division Multiplexing
• B. Time Division Multiplexing
• C. Code Division Multiple Access
• D. Wavelength Division Multiplexing

Answer: (B)

The process described involves sending multiple signals over a common channel using successive time intervals, which accurately defines Time Division Multiplexing (TDM). In TDM, the channel is divided into time slots, where each signal gets a specific time interval to send its data. This prevents signals from interfering with each other since each uses the channel exclusively for its designated time period. TDM is particularly useful in digital communication systems where it maximizes the utilization of available bandwidth by allowing multiple users to share the same transmission medium effectively. Each user's data is transmitted in rapid succession, with the process cycling through all users in the system, thus enhancing overall network efficiency. In contrast, Frequency Division Multiplexing sends multiple signals simultaneously over different frequencies, while Code Division Multiple Access uses unique codes to allow multiple signals to occupy the same channel at the same time. Wavelength Division Multiplexing is specific to optical fibers and separates channels using different wavelengths of light. These processes do not utilize the concept of time intervals in the same way that TDM does.
