Download final.zip from the class web page. The archive contains final.mat with the arrays sig1, n, and s.

  1. Given a signal sig1 that looks like the plot below, find an AR or ARMA model to represent the signal.

  2. Given a representative noise sample n obtained by passing gaussian white noise through a linear filter, find the one pole - one zero coefficients that best represent that filter.

  3. Given the signal s which contains several copies of the signal sig1, with different scales, find the locations and scale of the copies.

  4. Design FIR and IIR Wiener filters to suppress the noise in s. Evaluate the performance of the filters.
