MATLAB Code Implementation for Instantaneous Frequency Estimation

This MATLAB-based instantaneous frequency estimation tool enables accurate calculation of signal instantaneous frequencies through algorithmic implementations. The program incorporates signal processing techniques such as Hilbert transform or time-frequency analysis methods to extract instantaneous frequency components. Users can deepen their understanding of instantaneous frequency estimation principles through examining the code structure, which typically includes signal preprocessing, analytic signal generation, and phase differentiation workflows. The implementation demonstrates practical MATLAB functions like hilbert(), diff(), and angle() for phase extraction and frequency calculation. Designed with user-friendly interfaces and clear visualization components, the program features intuitive controls and plotting functions that make it accessible even for users without extensive MATLAB programming experience. The code organization follows modular design principles, separating core algorithms from GUI components, making it both an educational resource and practical tool for real-world applications in signal analysis and processing.
