What are the differences between the LMS and steepest descent algorithms? (10%) 3. What are the differences between the LMS and Levinson algorithms? (10%) 4.

State the definitions or meanings of the following terms: a) Principle of orthogonality b) Hermitian and Toeplitz c) Ergodicity (15%) 7. Draw the block diagrams of the four basic classes of adaptive filters and state the physical meaning of them (or why they work in these ways.) (15%) 8. A linear prediction filter can be implemented in the lattice form based on the recursive equations of prediction errors, one of which is f f b e (n) = e (n) + k e (n-1) m m-1 m m-1 1) State the other recursive equations of prediction errors 2) Draw the block diagram of the lattice filter (let order=3, and input signal be x(n) ) 3) State the advantages of using the lattice form than using the direct form.
