Signal sequence of the DFT spectrum of the sample itself is a set of signals, so the DFT can be directly used to analyze the signal spectrum. Fast Fourier Transform is an effective and practical signal DFT algorithm. By DIT-FFT algorithm for detailed analysis, a simulated signal spectrum analysis computer software program, and gives the key algorithm C language program.
