Question

Quizplus · Accepted Answer

In FDM (Frequency Division Multiplexing), multiple carriers are used to carry multiple signals simultaneously over a single transmission medium. Each carrier is divided into smaller frequency bands, which are allocated to different signals. These smaller frequency bands are called subcarriers. Therefore, Option A) is the correct answer.

Option B) channel is incorrect as it refers to a specific frequency band assigned to a particular signal or communication.

Option C) WDM (Wavelength Division Multiplexing) is a similar concept to FDM but it is used in optical fiber communication systems to multiplex several optical signals onto a single fiber by using different wavelengths of light.

Option D) subscriber is incorrect as it refers to an individual or organization who subscribes to a particular communication service.
