Time Division Multiplexing (TDM) is a technique used to transmit multiple signals over a single communication channel by dividing the time into distinct intervals. Each signal is assigned a specific time slot, allowing them to share the same medium without interference. This method is commonly used in digital communication systems, such as telephony and data networks. In TDM, the sender transmits data in a sequence, with each signal being sent during its allocated time slot. This ensures that all signals are transmitted efficiently and in an organized manner. TDM is particularly useful in scenarios where bandwidth is limited, as it maximizes the use of available resources.
