Bandwidth with respect to Modulation Index of FM Solution

STEP 0: Pre-Calculation Summary
Formula Used
Bandwidth of FM Wave = (2*Frequency Deviation)*(1+(1/Modulation Index in FM))
BWFM = (2*Δf)*(1+(1/β))
This formula uses 3 Variables
Variables Used
Bandwidth of FM Wave - (Measured in Hertz) - Bandwidth of FM Wave is twice the sum of modulation index multiplied with modulation frequency.
Frequency Deviation - (Measured in Hertz) - Frequency Deviation in FM is defined as the way to describe the difference between the minimum and maximum extent of a frequency modulated signal and the carrier frequency.
Modulation Index in FM - Modulation Index in FM Wave is the ratio of frequency deviation (Δf) to the modulating frequency (fm).
STEP 1: Convert Input(s) to Base Unit
Frequency Deviation: 30 Hertz --> 30 Hertz No Conversion Required
Modulation Index in FM: 0.6 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
BWFM = (2*Δf)*(1+(1/β)) --> (2*30)*(1+(1/0.6))
Evaluating ... ...
BWFM = 160
STEP 3: Convert Result to Output's Unit
160 Hertz --> No Conversion Required
FINAL ANSWER
160 Hertz <-- Bandwidth of FM Wave

How is modulation index related to bandwidth?

The bandwidth of a frequency modulated signal varies with both deviation and modulating frequency. Increasing modulating frequency increases the frequency separation between sidebands. Increasing modulating frequency for a given level of deviation reduces modulation index.
