(b) Find the minimum meansquare error when the coefficients obtained in (a) is used. 3. Suppose that the coefficients of the 3tap adaptive FIR filter are set to zero initially, that is, w (0) = 0, w 1 (0) = 0, w 2 (0) = 0. The subscript represents coefficient number and the number inside the parenthesis represents time. The input signal to the adaptive FIR filter is given by x(0) = 1.1, x(1) = 0.3, x(2) = 0.8, x(3) = 0.2, x(4) = 1.2, x(5) = 0.25 and the desired signal is given by d(0) = 1, d(1) = 0, d(2) = 1, d(3) = 0, d(4) = 1, d(5) = 0 Find the output y(k), e(k) for k = 0, 1, 2, 3, 4, 5. Also find the coefficients w (k), w 1 (k), and w 2 (k) for k = 1, 2, 3, 4, 5. Assume that = 0.1. 1...
