A MATLAB simulation program implementing Short-Time Fourier Transform (STFT) with comparative analysis of different window functions and varying window lengths for time-frequency spectrum visualization
The averaged periodogram method calculates FFT results by segmenting an N-point finite-length sequence x(n), computing periodograms for each segment, and then averaging them. Bartlett's method implements this basic approach, while Welch's method introduces two key improvements: applying window functions before periodogram computation to ensure non-negative spectral estimates, and allowing overlapping segments to reduce variance. Code implementations typically involve data segmentation, window application, FFT computation, and result averaging.
