railway RRB JE (CBT I + CBT II) Mock Test 2024 Communication Systems Pulse Modulation Pulse Analog Modulation
If PAM is the power dissipated by the AM wave and Pc is the associated carrier power, then correct relation between PAM AND PC for distortion-less transmission is:
1
PAM = PC
2
PAM = 1.5 PC
3
PAM = 2 PC
4
PAM = 2.5 PC
