Concept:

In Synchronous TDM, frame duration is equal to bit duration

\(Frame \ duration=bit \ duration =\frac{1}{Data \ rate}\)

Calculation:

Data rate = 3 kbps.

\(Frame \ duration =\frac{1}{3 \ kbps}\)

Frame duration = 0.33 msec.

Time-division multiplexing (TDM)

  • Time-division multiplexing (TDM) is a method of transmitting and receiving independent signals over a common signal path by means of synchronized switches
  • At each end of the transmission line so that each signal appears on the line only a fraction of time in an alternating pattern
  • It is used when the bit rate of the transmission medium exceeds that of the signal to be transmitted
  • TDM is used for digital signals
