Detailed explanation-1: -In synchronous TDM, each input connection has an allotment in the output even if it is not sending data. In synchronous TDM, the data flow of each input connection is divided into units, where each input occupies one input time slot. A unit can be 1 bit, one character, or one block of data.

Detailed explanation-2: -What is frequency-division multiplexing (FDM)? In frequency-division multiplexing (FDM), multiple signals are combined for transmission on a single communications line or channel, with each signal assigned to a different frequency (subchannel) within the main channel.

Detailed explanation-3: -Frequency-division multiplexing (FDM). Bandwidth on a communications link is divided into subchannels of different frequency widths, each carrying a signal in parallel with the other signals. Analog radio transmissions commonly use FDM to multiplex signals across radio waves.

Detailed explanation-4: -Asynchronous TDM Time slots are allocated to only those devices which have the data to send. Therefore, we can say that Asynchronous Time Division multiplexor transmits only the data from active workstations. An asynchronous TDM technique dynamically allocates the time slots to the devices.
