Query: Prony, Pad\'e, and Linear Prediction for Interpolation and Approximation
  in the Time and Frequency Domain Design of IIR Digital Filters and in
  Parameter Identification   Model based signal processing or signal analysis or signal representation has
a rather different point of view from the more traditional filtering and
algorithm based approaches. However, in all of these, the names of Prony,
Pad\'e, and linear prediction come up. This note examines these ideas with the
goal of showing they are all based on the same principles and all can be
extended and generalized. A particular application is the frequency sampling
design of IIR digital filters.
