For an amplitude modulated wave, the maximum amplitude is found to be 10 V, while the minimum amplitude is 2 V. What is the modulation index ?

Text Solution

Verified by Experts

Here, `A_(max) = 10 V and A_(min) = 2 V, mu_a= ?`
`mu_a = (A_(max)-A_(min))/(A_(max)+A_(min)) = (10-2)/(10+2)`
`=0.67`.
