##### A DT LTI system having input x[n] and output y[n] is

A DT LTI system having input x[n] and output y[n] is described by the block diagram shown. Unlike HW #18, leave the sign of the input to the adder that takes the output of the 1/6 scalar multiplier the way it is. Do not change it. Do change the upper scalar multiplier from a value of 2 to a value of 4. These changes will result in a small difference in the transfer function and the pole zero plot that results, in comparison to HW #18. 2. Assume that the system input is x[n] = u(n] and that y[-1] = 1 and y[-2]=-1. Use the UZT in order to obtain the output y[n] of the system for n greaterthanorequalto 0. Use MATLAB to plot the result
