Speaking as someone who hasn't the faintest clue of all this digital stuff, I can't praise Paul's article highly enough -

Admittedly I got a bit lost towards the end, but I do now have a rough understanding of the principles, which is a whole lot more than I had to begin with.

It's a brilliantly written, clear, writeup which deserves to be published far and wide.

Well done.

************************ 


I wrote a non-mathematical introductory article about how
forward error correction works.

There's a lot of material on the web about FEC but most
of it is very technical and tends to concentrate on one or
another particular coding scheme. I couldn't find anything
that demonstrates and really explains in simple terms the
essential principle of it.

So I thought I'd try to write something, perhaps to see if
I can understand it myself.

The article should appeal to anyone who's wondered how 'coding'
a message, which increases its bandwidth and reduces its S/N,
can actually lead to greatly improved communications.

Whether I've succeeded or not, the reader will have to judge.
