Task 1 A non-minimum phase system H(z) can be decomposed into a minimum phase system Hmin(z) and an allpass system Hap (2) such that: H(z) = Hmin (2) Hap (2) Write a MATLAB function that accepts the coefficients of H(2) and outputs the coefficients of Hmin (2) and Hmin (2). The syntax of the function is as follows: function [b_min, a_min, b_ap, a_ap] = Decompose (b, a) This function generates minimum phase and allpass decomposition finputs: 'b' & 'a' = row vectors containing numerator and denominator coefficients of given system Soutputs: 'b_min' & 'a min' row vectors containing numerator fand denominator coefficients of minimum phase system 8 'b_ap' & 'a_ap' = row vectors containing numerator and %denominator coefficients of allpass system Hint:- Determine locations of zeros/poles and identify which of those are outside the unit circle. Questions: Test your function for the following system functions given below. 1-2z-1 (i) H(2) - 1-4--1 1-2z-1 + 7z-2 (ii) H(2) = 1-5z + 15z-2 In each case, write the transfer functions of resulting minimum phase and allpass systems
