information theory - live example

powerpoint for lecture on information theory+colour printer -> slides without equations:(

powerpoint for lecture on information theory+mono printer -> slides with equations:)

ergo, colour printer driver is an erasure channel with memory and rather non random behaviour and information rate is massively reduced :-(

pushing this as an example for explaining shannon is a bit of a the sense that the "physical channel" is the printer and the colour printer should have more capacity in some sense, although I suppose the point is that the "noise" process" is an erasure channel that removes (say) bytes that code yellow but not bits that code white/black...
