Download final.zip from the class web page. The archive
contains final.mat with the arrays sig1, n, and
s.
- Given a signal sig1 that looks like the plot below, find an AR or
ARMA model to represent the signal.
- 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.
- Given the signal s which contains several copies of the
signal sig1, with different scales, find the locations and
scale of the copies.
- Design FIR and IIR Wiener filters to suppress the noise
in s. Evaluate the performance of the filters.
