Description: Curriculum design, signals and systems courses designed to familiar FFT calculation process, the combined DFT physical significance and experimental results to deepen the understanding of the Fourier transform. The article first a simple signal using MATLAB FFT simulation obtained spectrogram followed by the completion of the FFT of the C language, combined with MATLAB plotting and data processing functions come under the C implementation of the FFT results Finally, the discussion and analysis of the experimental results .
