Modulation index of wideband FM systemA. >1B. < 1C. = 1D. None
Question
Modulation index of wideband FM systemA. >1B. < 1C. = 1D. None
Solution
The modulation index of a wideband FM system is typically greater than 1. So, the answer is A. >1.
Here's a step-by-step explanation:
-
Modulation index (β) is a parameter that describes the depth of modulation in frequency modulation (FM) and phase modulation. It is the ratio of the frequency deviation (Δf) to the modulating frequency (fm).
-
In a wideband FM system, the frequency deviation is large compared to the modulating frequency. This means that the modulation index (β = Δf / fm) is greater than 1.
-
Therefore, the modulation index of a wideband FM system is typically greater than 1.
