Question

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. $89.33W$
• B. $64.85W$
• C. $79.36W$
• D. $102W$

Answer 1

The correct option is C $79.36W$

Modulation Index $=0.8$
$Pc=124W$
Power in sidebands may be calculated as $=m^2\frac{Pc}{4}$
$={0.8}^2\times \frac{124}{4}$
$=79.36W$
