For an amplitude modulated wave, the max...

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

Text Solution

Verified by Experts

`mu = (A_m)/(A_c)`
where, `A_m= A_("max") - A_("min") = 10-2=8`
`A_c= A_("max") + A_("min")= 10+2=12`
`:. " " mu = (8)/(12)= (2)/(3)`.
