What does Frequency Division Multiplexing allow?

• A. Multiple signals to coexist on the same frequency
• B. Multiple AM radio stations to coexist within a single band
• C. Single channel communication
• D. Reduction of bandwidth usage

Answer: (B)

Frequency Division Multiplexing (FDM) is a technique that allows multiple signals to be transmitted simultaneously over a single communication channel by allocating a distinct frequency band to each signal. This means that multiple information signals can coexist within the available bandwidth of the channel without interfering with each other. Each signal is modulated onto a different carrier frequency, enabling the simultaneous transmission of different signals in parallel. The context provided in option B highlights that multiple AM radio stations can coexist within a single band. This is a prime example of FDM in action, where individual stations are assigned specific frequencies within the AM band. This allocation ensures that each station can transmit its audio signal without causing interference with others, allowing listeners to tune in to their desired frequency without disruption. In contrast, other choices do not accurately represent the capabilities of FDM. For instance, the idea of multiple signals coexisting on the same frequency does not align with FDM's principle, as FDM requires distinct frequency bands for each signal. Single channel communication pertains to the situation where only one signal is transmitted at a time, which does not utilize the multiplexing advantages. Lastly, FDM is not primarily designed for reducing bandwidth usage; rather, it optimizes the use of the available bandwidth by allowing diverse
