Frequency-division multiplexing

Question

Illustrate the term Frequency-division multiplexing with example?

Answer 1

Frequency-division multiplexing (or FDM) is an analog method which can be applied when the band width of a link (in Hz) is bigger than the combined bandwidth signals to be transmitted.

In FDM, signal produced by each sending device modulates distinct carrier frequencies.

These modulated signals are then combined into a single composite signal which can be transmitted by link.

Example: Radio, television broad casting and so on.
