The total transmitted power for an AM system is given by:
Pc = Carrier Power
μ = Modulation Index
The above expression can be expanded to get:
The total power is the sum of the carrier power and the sideband power, i.e.
Calculation:
Given: Pc = 100 W and μ = 1
We can write:
The total sideband power = 50 W
