Q. What is the maximum transmission efficiency?

A
67.88%
B
33.33%
C
73%
D
54.03%
Solution:

The maximum transmission efficiency is 33.33%. It is so because 2/3rd of the total power is contained in the carrier, which conveys no useful information. Thus, only 1/3rd of total power has useful information which is transmitted. This happens in case of SSB-SC Modulation, where the carrier is suppressed and only either of the sidebands is allowed to pass.
