Q.  Bandwidth required in SSB-SC signal is (fm is modulating frequency):
- Published on 13 Oct 15

a. 2fm
b. < 2fm
c. > 2fm
d. fm

ANSWER: fm
 
In an amplitude modulated wave, total bandwidth required is from fc + fm to fc - fm

i.e. BW = 2fm where fc is carrier frequency.

In SSB-SC transmission, as the carrier and one of the sidebands are suppressed, the bandwidth remains as fm.
