This question was posed to me by my school principal while I was bunking the class.

Asked question is from Frequency Division Multiplexing topic in division Radio Transmitters, Communication Receivers, Multiplexing and Demultiplexing of Avionics

Answer 1

The correct choice is (a) Subcarrier

Best explanation: Each signal to be transmitted feeds a modulator circuit. The carrier for each modulator (fc) is on a different frequency. The carrier frequencies are usually equally spaced from one another over a specific frequency range. These carriers are referred to as subcarriers.
