Resource Overview
MATLAB implementation for spectral refinement analysis featuring ZOOM-FFT technique with spectrum magnification capabilities for detailed frequency domain examination
Detailed Documentation
This program performs spectral refinement analysis using MATLAB computational environment. The implementation utilizes ZOOM-FFT (Zero Padding Optimized Fourier Transform) technique to achieve high-resolution spectral analysis through frequency band zooming and interpolation algorithms. The system incorporates a spectrum magnification feature that employs signal windowing and frequency bin interpolation to enhance visualization of spectral details. Key MATLAB functions include fft() for base transformation, hanning() for windowing operations, and interp1() for spectral interpolation. The algorithm employs decimation and frequency shifting techniques to focus on specific frequency bands while maintaining computational efficiency through selective processing of relevant frequency ranges.
