OK, let's say you have cable TV.
The TV signal's come thru the coaxial cable in mpeg 2 format.
But what I don't get is how can all the channels come into the same cable all at the same time won't their be constructive or destructive interference??? I just don't get how one can seperate the signals from each other.
And my other problem is how the computer knows what channel data we want. If their is a tuner in each TV then how does it filter out the correct
data for the TV.
Note I know the basic's of LC circuit's so spare nothing.
What I am trying to understand is how the tv can seperate the electromagnetic waves for each channel and how the tuner (if any)
works to filter the data.
