Solution :

Expalnation:

 As We know that Time-division multiplexing is a digital process that can be applied when data rate capacity of  transmission  medium is greater than data rate required by sending and receiving devices . But in the “Synchornous Time-Division Multiplexing” in all the devices Multiplexer allocates  same time slots in each device whether these devices has any thing to transmit or  not.

For example if we assign a time slot ‘W’ only to device ‘K’ and for each time time device ‘K’ has enable to send its data in given time if the device  ‘K’ has no data or device ‘K’ is enable to send data the time slot remains empty.

      As we know that Time slots is a group of frames and each frame contain one complete cycle of  time slots. We also know that if a system or computer has m imput lines than each frame requires m slots and each slot carrying data from specific line input line.

If in the system all input devices sharing a link at same data rate than each device has same time slot for each frame. The time slots given to device occupy the same same location in each frame .
