Max. Marks : 100
Instruction : Answer any five full questions.
1. a) Explain the Transversal filter with neat diagram.

b) Briefly explain the four basic classes of adaptive filtering applications.
12
2. a) Derive the necessary and sufficient condition for the process u(n) to mean ergodic in the mean-square-error sense.
10
b) Consider a MA process x(n) of order two described by the difference equation x(n) = v(n) + 0.7 v(n–1)+0.25 v(n–2) where v(n) is a zero-mean white noise process of unit variance. The requirement is to approximate this process by AR process u(n) of order M. Do the approximation for the following orders a) M = 2 b) M = 5 c) M = 10
