Please show the steps. I'm confused.
(6 Pts.) Suppose we have a discrete-time signal [n] defined as 3л t[n] = Al cos kit 32 + Azcos (FM) where A1, A3 and kq are known to be positive integers. You compute the 32-point DFT of {z[n]} 20 and observe that the magnitude of {X [k]}}=o is as shown below: 31 k0 as 30 25 20 Hem 15 10 5 ppppplesesore peoppilleppe 90 10 15 20 90 36 Find the values of A1, A2 and ki.
