Find the Discrete Fourier Transform of the following sequences :
Assume N = 4 and the samples taken for a duration T = 2pi
1. x[k] = {1, 1, 0, 0}.
Ans : {2, 1-j, 0, 1+j}
2. x[k] = {1, 2, 1, 2}
Ans : {6, 0, -2, 0}
3. x[k] = {6, 0, -2, 0}
Ans : {4, 8, 4, 8}
4. x[k] = {4, 8, 4, 8}
Ans : {24, 0, -8, 0}
