In this experiment, we have found the 4-point DFT and 8-point DFT and analysed the spectrum of the utput signal.
We have analysed that as the values are increased in 8-point DFT, the quality of the spectrum is improved.
We have concluded that as the order N increases, the frequency spacing reduces, which in turn reduces the approximation error in the representation of spectrum.

Good..you can add more on the algorithm of discrete Fourier transform..
