Subject: How do I calculate THD in MATLAB? From: chikha said Date: 2 Feb, 2011 06:58:03 Message: 1 of 9 
How can I calculate THD (Total Harmonic Distortion) in a MATLAB file? Please note, I know I can do this in Simulink, I am looking for a way to do this from MATLAB directly.

%Following the proposed solution by Wayne, I will explain a method in order to %compute THD using the FFT.
