What is the modulation index of an FM signal having a carrier swing of 100 kHz when the modulating signal has a frequency of 8 kHz?

Text Solution

Verified by Experts

Given:Carrier swing =100kHz, `f_(a)`=8kHz, From the defining equation, `m_(f)=(Delta f)/(f_(a)`,First determining `Delta f, Delta f=("Carrier Swing")/(50kHz)`=`(100xx10^(3))/(2)`,Now substituting into the equation for `m_(f)`, `m_(f)=(50xx10^(3))/(8xx10^(3))=6.25`
