Question

Time Division Multiplexing (TDM) allows multiple signals to share a channel by:
  1. A
    Using different carrier frequencies for each signal
  2. B
    Allocating each signal a time slot in a repeating frame
    Correct
  3. C
    Frequency hopping between signals
  4. D
    Amplitude 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.
