Not sure if this is more a question for the physics forum or here, but ill start here.
I've been doing some reading on signal to noise calculations for video applications. In the reading it says that when you drop a certain signal by 2, the noise portion of it will only drop by
sqroot(2).
Don't really unsderstand where the sqroot comes in. Can anybody clear this up for me?
