How to Do FFT in MATLAB
Channel: MATLAB
Category: Science & Technology
Description: Learn how you can do Fast Fourier Transform (FFT) in MATLAB. It starts with generating a synthesized signal and then using the FFT function to convert the signal from the time domain to the frequency domain, finally showing how to determine the sinusoid components of the signal in the frequency domain. Zero-padding and windowing methods are also introduced for spectrum analysis when the signal duration does not contain an integer number of signal cycles.
