Numerical - Side band power calculation

Q.  Calculate the power in one of the side band in SSBSC modulation when the carrier power is 124W and there is 80% modulation depth in the amplitude modulated signal.

a. 89.33 W
b. 64.85 W
c. 79.36 W
d. 102 W

ANSWER: 79.36 W
 
Modulation Index = 0.8
Pc = 124W
Power in sidebands may be calculated as = m2 Pc/4
= (0.8)2 * 124/4
= 79.36 W

    P=Pc(1+(m^2)/2)=163.68 (2dp)
    Then, Psb=(P-Pc)/2=19.84 W
