USB (Upper Side Band) is the band of frequencies _________(a) below ca

1.	USB (Upper Side Band) is the band of frequencies _________(a) below carrier frequency in AM spectrum(b) above the carrier frequency in AM spectrum(c) includes the carrier frequency in AM spectrum(d) is the center frequencyThis question was posed to me in class test.I want to ask this question from Need of Transducers in chapter Receivers & Transducers of Analog Communications
Answer» The correct CHOICE is (c) INCLUDES the CARRIER frequency in AM spectrum The best explanation: Upper Side Band is the band of FREQUENCIES above the carrier frequency that lies in AM spectrum. It is a part of the shifted spectrum obtained after amplitude MODULATION.
