this is a system described by this 2nd order difference equation:
y[n] + y[n-1] + 1/4 y[n-2] = x[n]

            jw
find H( e ) ?
find the expanded form using Partial Fraction Expansion?
find the impulse response h[n]?
find the step response S[n] using convolution?
is this system oscillatory???
plzzz help me with this problem....
