In a 100% amplitude modulated signal, the power in the upper sideband when carrier power is to be 100 W and modulation system SSBSC, is
100 W
66 W
50 W
25 W
Answer: Option
Explanation:

Modulation index = 100% 1

Pc = 100 W

Yes @Raisul,

But that is the TOTAL power of the sidebands. Since the problems say that the system is SSBSC, we need the power for a single sideband only. That's why we divide it by 2.

Pt=pc (1=ma^2/2)

this total power has collaboration in career and sidebands as there are two side-bands.

So power should be pcma^2/4.

Isn't power in sidebands is equal to (m^2*Pc)/2?
