(a)Find the z-transform of the signal x(n) given by x(-1)=1, x(0)=5, x(1)=2 and x(n)=0 for all other value of n.
(b)Find the signal h(n) whose z-transform is H(z)=5+0.1z-1+z-3
(c) Use z-transform to find y(n)=x(n)*h(n)<------->H(z)X(z). Note: this should explain how the convolution array works and why the MATLAB conv can be used to multiply two polynomials.
