I'd never > even heard "jury rig" in this context before.really? say, it's the Apollo 13 mission, and they need to get some more juice to restart the Orbiter than the batteries in the Orbiter have to give. what to do, what to do? i wouldn't have expected they had the spare cables lying around (since every gram of weight is accounted for), but they were able to hook up the power supply of the LEM to the Orbiter with cables that went right through the hatch so that they had the extra one or two amps needed to restart all of the electronics in the Orbiter that were necessarily shut down (since they lost their fuel cells in the explosion). i cannot think of another term for that. what would be a better term?> Not to be confused with "rigged jury".as in Bush v.

That's what I meant. I suppose it could now take on a new meaning and we could call it Jerry-rigged (referring to Avins) because I'll bet he has some kind of record doing this sort of thing .. a very clever guy. Fred

I should have said "Brent"it was Brent's idea, and it makes a bigger difference if you're viewing the thread in Google Groups. i did adopt it. but i'm sorta hypocritical, since i was advocating starving the troll. Fred, there was something else you said in another thread that i was gonna respond to, but i didn't have time at the moment and now i can't find it. might you know what it was? -- r b-j rbj@audioimagination.com "Imagination is more important than knowledge."

But the tumult soon subsides. Time makes more converts than reason." -- Thomas Paine (1776) Still, tumults are rare in math and there isn't much of one here either. Everyone with a Ph.D. in math has already or will soon readily admit that "matched filtering" isn't the best term. North would have been better off just calling it a "partial matched filter" or just the "North filter." Now we are stuck with calling the deconvolution of a matched filter output "the pure match filter" or the "complete match filter" or "matching only" filter. Bret Cahill "All is number."
