Consider the system whose input-output relationship is defined as
y[n] -y[n – 1] +y[n – 2] = x[n].
a) Sketch the block diagram of this system ensuring this difference equation defined above either in Direct Form-l or
Direct Form-ll.
b) Find the system frequency response, H(e^).
c) Find the impulse response of the causal system, h[n] by applying inverse DTFT to the H(e).
d) Find the system output when x[n] =A)" u[n] is applied to this system.
e) An equalizer system for this system is defined as Hinv(e^) = H-(eA). Find the corresponding impulse
response for the equalizer system which will be the inverse DTFT of Hin(e).
