Most Upvoted Answer
In a frequency modulation system, maximum frequency deviation allowed ...
Concept:
In FM (Frequency Modulation), the modulation index is defined as the ratio of frequency deviation to the modulating frequency.
Mathematically, this is defined as:

mf = Modulation index
Δf = Frequency deviation
fm = Modulating frequency
Calculation:
Given Δf = 1000 Hz = 1 kHz
fm = 1 kHz
