All the Time Division Multiplexing Questions & Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of Time Division Multiplexing.Time-division multiplexing is represented as TDM. In TDM, the signals get transmitted by occupying different time slots. Source signals are divided into multiple frames each having separate time slots. When the frame is transmitted over the particular slot, the next frame uses the same channel to get transmitted and the process is repeated simultaneously. Only digital signals are preferred best over analog signals while multiplexing.There are four types of TDM available: Asynchronous TDM, Synchronous TDM, Interleaving TDM, and Statistical TDM. Advantages of TDM are it protects data from degradation, reduces latency compared to other methods of multiplexing, increases bandwidth and it fixes failures. Disadvantages of TDM are the entire system will fail if there exists one channel failure, it takes a lot of time to shift from one channel to another, more complex than other methods, it requires an expensive regenerative repeater to regenerate the signal. Applications of TDM are in Hospitals, Telephony, Television, Satellite communication, and LAN networks.1). Time Division multiplexing is a ________ method?
