An LTI filter is described by the difference equation
(a) What is the impulse response h[n] of this system?
(b) Obtain an expression for the frequency response of this system.
(c) Sketch the frequency response (magnitude and phase) as a function of frequency.
(d) Suppose that the input is
for –∞>n>∞. Obtain an expression for the output in the form .
(e) Suppose that the input is
where u[n] is the unit-step sequence. For what values of n will the output y1[n] be equal to the output y[n] in (d)?
