Question
Please can u solve problem 2 and three they are related thank you ?
EE306 HW5 Problem 1 form of X(:)-e? A Problem 2 Solely based on the formulas and (n+1) a" afn] (1) determine the z-transforms of the following sequences: (a) r[n] = (n-1) u[n] (b) r[n] = (-1)"2 u[n] (c) r[n] = cos(bn) u[n] Hint: Remember that cos and sin yield expressions in terms of complex exponential functions. Problem 3 Given that w, r, A are all real, put the 2-transforms you obtained in Problem 2 in the form of single fractions with only real coefficients. Hint: ata - 2 Re(a) ; a-a' = 2j Im(a) ; a** = a ; aa* = Ja; (a3)* = a*8".
