| Jun 12, 2012 at 19:36 | comment | added | Graeme | I'm imagining a sequence of polynomial interpolators that are each active on a short range of samples. So, as a batch of new samples comes in, you'd construct an interpolator that's only active in a defined interval. Your continuous-time approximation to the sampled signal consists of these polynomials. (I'm thinking Lagrange, but Chebyshev is probably the same thing. I don't recall if Chebyshev interpolators match the sample points exactly. If not, you'd get discontinuities when switching between interpolators.) | |
