among other cleanups, i removed this line (which was on channel):
One of possibly millions of often times pointless wavelengths decoded by a television system.
am i wrong to see it as a duplicate meaning? what is 'pointless' implying? it is quite possible i have misunderstood.
my edits here are solely from the basis of cleanup, i am far from an expert. anyone who knows more is strongly encouraged to fix any mistakes, including re-opening communications channel.
also, i guess this article should not be in category:telecommunications stubs since some of it is about non-telecom. am i right about this?

I've added a definition of Channel from Shokrollahi's "LDPC Codes: An Introduction" (see references). This is the clearest, most concise explanation of a channel I have seen. I've pasted it verbatim, so it will probably need to be worked into the article better. I figured the value and clarity of this definition outweighed any temporary lack of flow. Please be sure to retain the simplicity in any further editing!
I'm currently unclear whether Shokrollahi's definition is restricted to a memoryless channel, or can it be extended by defining each 'alphabet member' to be a sequence of symbols. Anyone care to clarify? Perhaps the definition also requires links to articles explaining 'alphabet' and other technical terms, or a rewrite to eliminate those terms?
