TDM, or time-division multiplexing, is a method of transmitting multiple signals over a single communication channel by dividing the channel into different time slots. Each signal is assigned to a specific time slot, and the signals are transmitted sequentially. This allows multiple signals to be transmitted simultaneously without interference.
TDM is an important technology that is used in a wide variety of applications, including telecommunications, data communications, and video transmission. It is a key technology that enables the transmission of multiple signals over a single channel, which can save on bandwidth and other resources. TDM has been used for many years, and it continues to be an important technology today.
