4. (25 points) Consider the (causal) IIR filter described by the difference equation y[n] – 0.25y[n – 1] = x[n] +0.5x[n – 1] (i) Determine the system function of this filter (including its region of convergence). Is the filterstable? (ii) Using z-transforms, determine the response y [n] of this filter to the two-sided input se… Show more… Show more Engineering & Technology Electrical Engineering ENEE 322 Share QuestionEmailCopy link Comments (0)
