About this document
FFT Spectral Analysis in MATLAB by cejavier is a document available to read on EtoBox.
This document discusses using the fast Fourier transform (FFT) for spectral analysis of a noisy time domain signal. It creates a signal with 50 Hz and 120 Hz sine waves, adds random noise, and takes the FFT to find peaks in the power spectral density at 50 Hz and 120 Hz, identifying the original frequency components buried in the noise.
