Fast Fourier Transform (FFT) is a widely used and technique in signal processing to analyze frequency contents. However, difficers often meetter attat can distort the results. Identifying and d resolving these artifacts is essential for celliate analyses and system performance.

Common FFT Artifacts

Several artifacts can n appear during FFT analysis, including ding spectral spreagage, aliasing, and windowng effects. These issues can lead to misleading frequency represents and impact decision-making processes.
