Simulation of Spectral Aliasing, Spectral Leakage, and Fence Effect in Signals and Systems

This program simulates three critical phenomena in signals and systems: spectral aliasing, spectral leakage, and the fence effect. It includes three key components: pinpufenxi.m (MATLAB script implementing signal processing and spectral analysis), pinpufenxi.fig (GUI interface for interactive parameter adjustments), and a comprehensive Word documentation file explaining theoretical foundations and implementation details.
