If one were to be bothered to work out the phase from this, tan^-1 im(H(wj))/re(H(wj)), I dare say it might be possible to see what it is about n=5 that keeps it nearly zero for w<1 (for 'w', read 'omega'). I have to say I'm not even remotely tempted, far too busy doing other things!

this is the best post i've ever read, may i put it on a t-shirt?
