試題 :


1. Draw the signal flow diagram for an order-M Wiener filter with proper
   labeling




2. Write a pseudo program to implement the Wiener filter in problem 1 using
   LMS algorithm



3. For the MMSE lenear prediction problem, in which the desired signal u(n)
   show that the Wiener-Hopf equation can be derived from the priciple of
   orthogonality.



4. The error performance surface og the Wiener filtering problem J(w) can
   be expressed as the following term:
                          H
   J(w) = Jmin + (w - w_0) R(w - w_0)
                                             H
   what are the meaning of Jmin and (w - w_0) R(w - w_0)




5. Based on the Levinson algorithm, three sets of parameters can be found
   for representing a WSS random process,  what are the three sets of
   parameters?
   (please give a brief descriptions about the meaning of parameters)
