USB (Upper Side Band) is the band of frequency
a.) Above the carrier frequency
b.) Includes the carrier frequency
c.) That lies in AM spectrum
d.) Both a) and c) are correct
Correct Answer: d) Both a) and c) are correct
Explanation:
USB (Upper Side Band) is the band of frequency above the carrier frequency that lies in AM spectrum. It is a part of the shifted spectrum obtained after amplitude modulation. It is denoted by ω
c+ ω
m where ω
c is the carrier frequency and ω
m is the modulating frequency.
