Questions
A sinusoidal carrier voltage of frequency 1.5 MHz and amplitude 50 V is modulated by sinusoidal voltage of frequency 10 kHz producing 50% modulation. The lower and upper sideband frequencies in kHz is
detailed solution
Correct option is A
Given : fc=1.5MHz = 1500 KHz , fm=10 kHz ∴LSB=fc−fm=1500 − 10 = 1490 kHz and USb=fc+fm=1500 +10 = 1510 kHzTalk to our academic expert!
