Question

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

Answer 1

Answer:

carrier power is 16.1 kW

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

$P = 1 + \frac{m^2}{2} * carrier power$   ...............1

put here all value in equation 1  we get carrier power

$P = 1 + \frac{m^2}{2} * carrier power$

$20 = 1 + \frac{0.7^2}{2} * carrier power$

solve it we get

carrier power = 16.1

so carrier power is 16.1 kW
