Question
Time Division Multiplexing (TDM) allows multiple signals to share a channel by:
- AUsing different carrier frequencies for each signal
- BAllocating each signal a time slot in a repeating frameCorrect
- CFrequency hopping between signals
- DAmplitude coding each signal differently
Correct answer
Allocating each signal a time slot in a repeating frame
Explanation
TDM interleaves time slots from different signals. A T1 line carries 24 voice channels (each 64 kbps) by TDM → 1.544 Mbps total. Contrast with FDM which separates in frequency domain.
