Mini Program for Implementing ZoomFFT Frequency Refinement
A compact utility that performs ZoomFFT frequency refinement analysis, featuring configurable zoom bands and spectral resolution for enhanced signal processing applications.
MATLAB Implementation of Spectral Analysis with ZOOM-FFT Technique
In spectral analysis, the data length N and sampling frequency fs determine the frequency resolution df=fs/N. To enhance resolution, ZOOM-FFT is commonly employed. This article provides MATLAB code demonstrating how ZOOM-FFT refines spectral resolution through interpolation and resampling.
