# Modulation Problem

Started by March 31, 2004
```If linear modulation systems are to be compared on an equal peak power basis
(all have equal peak signal values), show that:
A. SSB has a (S/N)out that is 3 dB better than DSB.
B. SSB has a (S/N)out that is 9 dB better than AM.

Help with this problem would be greatly appreciated. Thank you in advance.

You'll have better luck getting help on homework problems if you showed some
effort in trying to solve it yourself...how far you got and where exactly
you are stuck.
If you have trouble even getting started, what part the problem description
baffles you?

On this specific one...
on part A, what does a change in power of a signal by 3dB signify to you -

Cheers
