A broadcast AM transmitter radiates 50 ...

A broadcast `AM` transmitter radiates ` 50 kW` of carrier power . What will be the radiated power at `50%` modulation ?

Text Solution

Verified by Experts

The correct Answer is:
56.25 kW

`P_(t) = P_( c ) ( 1 + (mu^(2))/(2)) = 50 ( 1 + (1)/(8))`
`= (450)/(8) = 56.25 kW`
