Q1:

If γ = (S0/N0)/(Si/Nm) where S0 and S1 are signal power output and signal power input and N0 and Nm are noise power output and noise power input, the value of γ for SSB-SC and DSB-SC amplitude modulated system respectively are

A 1 and 1

B 1 and 2

C 2 and 1

D 0.5 and 0.5

ANS:A - 1 and 1

SSB - SC and SSB - DB have γ = 1 and are similar from noise point.
