a[n] = 6-point DFT transform of a sign defined as Discrete-Time a [n] = [2 5 3 8 4 0] is indicated by A [k]. (So a [n]  A [k]) On the other hand, since another N = 6-point AFD conversion pair is defined as b[n]  e j2626.8.k.A*[k]; Calculate b[3] and specify it in response. TIP: Starting from the multiplication of the complex-conjugate of A[k] by the exponential expression specified, determine the sequence b[n] in the Time-Space and answer the question.
