Question:
What is electronic noise?



Replies:
Imagine that you are in a really big room, which is very quiet. Way across the room somebody is whispering and you want to hear them from where you are. You put a microphone in front of you, with an amplifier, and make the amplifier amplify alot, trying to make that tiny voice become loud enough to hear. In the end you cannot just amplify endlessly, all you will be amplifying is electronic noise. You pick up that hummmm in the speakers, and you don't hear the tiny voice across the room -- its there on the speakers, but it is drowned out by the noise from the electronics.

You cannot amplifiy something, make it bigger, without degrading it just a bit. Just like you cannot make perfect copies on an office copy machine. copy copy copy, and eventually it gets fuzzy. same with amplifiers. usually tho the "voice" is strong enough that you don't NEED to amplify that much, and you can hear it out the speakers OK.
