Chuck, thanks for the explanation! One question about this -- would working back from the spectrum possibly mean that you wouldn't necessarily match any of the points (would this mean you could say the impulse response would not have a value of 1 at t=0)? This would be an interesting proposition, and maybe it might help temper the tendency of polynomial interpolation to deliver values >1 or <-1 when the curve has a maximum or minimum between samples? I'm not sure if that would be the result, but I like the sentiment. =o)
Yes, there are some situations where we could construct something that looks good on the face of things, but actually behaves poorly. However, there are a number of free variables involved. I will try to work through an example (so that I can figure it out).
Anyway, thanks again.
