Signal to noise ratio

[goldfinder]

Hey zindex666 - in real signal processing snr can be a overcome using digital signal processing. I have used the digitall signal processing to pop signals out of noise where the signal level was a 1000 times lower that the noise level. All that is needed is the signal characteristics which are usually different that the characteristics of the noise.

One thing I found out if you don't know what you are looking for, you will likely filter it out and end up with nothing.

Or like the Cheshire Cat said to Alice, "If you don't know where you are going, then any road will get you there."

"Which road do I take?" asked Alice.
"Where do you want to go?" responded the Cheshire Cat.
"I don't know." Alice answered.
"Then" said the cat "it doesn't matter."
