Detailed Documentation
This article presents my custom-developed FFT (Fast Fourier Transform) and DTFT (Discrete-Time Fourier Transform) programs designed for spectral analysis applications. The implementation includes comprehensive MATLAB code featuring optimized algorithm structures for efficient frequency domain computation. Additionally, the Rife method - a specialized spectrum correction technique for improving frequency estimation accuracy - is implemented with proper windowing functions and interpolation algorithms. The provided code demonstrates practical applications through visualized results with detailed plotting functions that display magnitude spectra, phase responses, and corrected frequency components. All programs have undergone thorough debugging and validation to ensure robust performance and accurate spectral characterization.
