Teaching TN TRB EC Mock Test Signals and Systems Discrete Fourier Transform (DFT) and Discrete Fourier Series (DFS) Properties of Discrete Fourier Transform
The first six points of the 8 point DFT of a real-valued sequence are 5, 1 – 3j, 0, 3 – 4j, 0 and 3 + 4j. The last two points of the DFT will be respectively:
1
0, 1 – 3;
2
0, 1 + 3j
3
1 + 3j, 5
4
1 – 3j, 5
