____Heya mate☺⬇️___

Q.What is modulation of index?If the maximum amplitude of an amplitude modulated wave is 10V and the minimum amplitude is 2V,what is the value of modulation index?

☺anyone please answer correctly don't unnecessary answer okk

Answer 1

Answer________________

(i). Modulation of index.

Modulation index for an AM wave is defined as the ratio of charge in the amplitude of the carrier wave to the amplitude of the original carrier wave.

_________________________________

(ii). find value of modulation index.

given,

Maximum amplitude, A max = 10V

Minimum amplitude, A min = 2V

So,

Modulation index,

u = ( A.max – A.min / A.max + A.min )

according to formula,

( 10 – 2 / 10 + 2 ) = 8/12

we get,

modulation index = 0.66.

Answer 2

Answer:

(i). Modulation of index.

Modulation index for an AM wave is defined as the ratio of charge in the amplitude of the carrier wave to the amplitude of the original carrier wave.

(ii). find value of modulation index.

given,

Maximum amplitude, A max

= 10VMinimum amplitude, A min = 2V

So,

Modulation index,

u = ( A.max – A.min / A.max + A.min )

according to formula,

( 10 – 2 / 10 + 2 ) = 8/12

we get,

modulation index = 0.66.
