Question

Frequency Division Multiplexing (FDM) allows multiple signals to share one channel by:
  1. A
    Sending them at different times
  2. B
    Allocating each a different carrier frequency
    Correct
  3. C
    Compressing each signal
  4. D
    Converting all to digital

Correct answer

Allocating each a different carrier frequency

Explanation

FDM assigns each message signal its own frequency band (sub-carrier). Radio stations use FDM — each occupies a specific frequency. Contrast with TDM where signals share time slots.
