An audio signal given by e(s)=15sin 2pi(...

An audio signal given by `e_(s)=15sin 2pi(2000t)` modulates a carrier wave given by `e_(s)=60sin 2pi (100,000t)`. If calculate (a) Percentage modulation (b) Frequency spectrum of the modulated wave.

Text Solution

Verified by Experts

Signal Amplitude , B= 15
Carrier amplitude A= 60
`m= (B)/(A)= (15)/(60)= 0.25`
`:. "Percentage modulation"= 0.25 xx 100=25%`
