Numerical - Side band power calculation
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
Correct Answer: c) 79.36 W
Explanation:
Modulation Index= 0.8
Pc = 124W
Power in sidebands may be calculated as = m2 Pc/4
= (0.8)2 * 124/4
= 79.36 W

- Two sides bands is39.68
One side band is 19.84 - RE: Numerical - Side band power calculation -Kola naresh (09/01/20)
- Correct answer is
One side band is 39.68 - RE: Numerical - Side band power calculation -Hari krishna (02/11/19)
- can u please explain how u get ((0.8)^2(124/4)=79.36)
