Compute the first 10 samples of the step response for the nonrecursive difference equation:
y(n) = x(n) -0.5x[n-1]-0.7x[n-2]
Indentify which of the following filters are recursive and which are nonrecursive. For each filter, indentify the coefficient ak and bk-.
(a) y(n) = (x[n] + x[n-1]+[n-2]/3
(c) y[n] = 0.5y[n-1]+x[n]-0.4x[n-1]
