Question
According to Carson’s rule, Bandwidth B and modulating frequency fm are related as*2 pointsB = 2(Δf + fm) HzB = fm HzB < 2fm HzB > 2fm Hz
Solution
According to Carson's rule, the bandwidth (B) of a frequency-modulated (FM) signal is related to the frequency deviation (Δf) and the maximum frequency of the modulating signal (fm). The rule is expressed as:
B = 2(Δf + fm) Hz
So, the correct answer is B = 2(Δf + fm) Hz. This equation means that the total bandwidth is twice the sum of the frequency deviation and the maximum frequency of the modulating signal.
