Question

An amplitude modulation transmitter radiates 20 KW. If the modulation index is 0.7, find the magnitude of the carrier power?

Answer 1

carrier power is 16.1 kW

Step-by-step explanation:

given data

power transmit P = 20 kW

modulation index m = 0.7

to find out

carrier power

solution

we will apply here power transmit equation that is express as

`P = 1 + (m^2)/(2) * carrier power` ...............1

put here all value in equation 1 we get carrier power

`P = 1 + (m^2)/(2) * carrier power`

`20 = 1 + (0.7^2)/(2) * carrier power`

solve it we get

carrier power = 16.1

so carrier power is 16.1 kW
