Distortion removal. a binary signal is sent over an imperfect channel which introduces distortion. the channel can be modeled as a discrete-time lti system with the transfer function h(z) = 1 βˆ’ 2.5 z βˆ’1 + z βˆ’2 1 βˆ’ zβˆ’1 + 0.7 zβˆ’2 . (a) determine the impulse response g(n) of the stable inverse of h(z). you may use the residue command in matlab. (b) using matlab, make a stem plot of h(n), g(n), and h(n) βˆ— g(n). check that you get an impulse. (c) using matlab (freqz) plot |hf (Ο‰)| and |gf (Ο‰)|, the magnitudes of the frequency responses. also plot the product |hf (Ο‰) Β· gf (Ο‰)|. what do you expect to get for the product? explain. (d) the binary signal x(
