Extracted text: 2) Frequency response of an LTI system is given as: H(e jo) = (1- 1.5 e jº)/ (1 – 4 e jo ). a) Find the input/output difference equation and the impulse response, h(n) of the system. b) Discuss the causality, stability and being FIR/IIR of the system. c) If an input signal, x(n) = (1/5)" u(n) + 3 &n), is applied to the system, find the output of the system, y(n), using DTFT methods.
