Signal processing is a technique for visualizing acquired data. Through methods like FFT transformation and integration, further data processing can be performed to identify peaks and display them. Signal processing finds extensive applications across various fields including communications, image processing, and audio analysis.
Typical MATLAB implementation involves: using plot() for initial data visualization, applying fft() function for frequency domain transformation, numerical integration methods (trapz() or cumtrapz()) for signal integration, and peak detection algorithms using findpeaks() function with appropriate threshold settings. The workflow typically includes preprocessing steps like filtering using filter() or smoothdata() to enhance signal quality before analysis.
