Question: Let x [ n ] = e 2 3 , for n = 0 , 1 , . . . , 5 and x [

Let x[n]= e2 3, for n =0,1,...,5 and x[n]=0 otherwise. (a) Find the length N of the signal x[n].(b) Using the DFT formula, find the DFT X[k], k =0,1,...,N 1. Hint: use the important geometric sum from Lecture 17.(c) From X[k] in Part (b), find x[n] using the inverse DFT formula
