Question

Higher frequencies can have more channels for a particular bandwidth.

(a) True

(b) False

I have been asked this question in final exam.

Question is taken from Electromagnetic Spectrum in section Introduction to Electronic Communication of Avionics

Answer 1

Right answer is (a) True

The best explanation: The benefit of using the higher frequencies for communication carriers is that a signal of a given bandwidth represents a smaller percentage of the spectrum at the higher frequencies than at the lower frequencies. It means that there can be more number of channels with the same bandwidth in higher frequency than lower frequencies.
