Question

The frequency response of a LZD system is given as;
H(e^jω) = (1- 2 e^–jω) / (1 – 0.5 e ^–jω )

a) Give the input/output difference equation of the system and draw the Direct II Form block diagram.
b) Give the system's impulse response h(n).
c) Discuss the causality, stability and FIR/IIR type of the system.
d) For input sign x(n) = (1/4)'' u(n) + 4 δ(n), find the output y(n) of the system by DTFT methods.
