How can i export all data points from FFT analysis Tool to workspace
显示 更早的评论
What i want to do is export all datapoints from FFT analysis tool for THD calculation, but i want to export all the harmonics and its output voltages to calculate the THD manually..if someone knows i would be greatful for your help...
thanks in advance

sps = power_fftscope(bdroot);
%Sampling time
Ts = sps.FFTdata.t(2)-sps.FFTdata.t(1);
%Samples per cycle
Sc = 1/(Ts*sps.fundamental);
%DC component
DC = sps.mag(1);
%Fundamental frequency
Fc = sps.fundamental;
%Total harmonic distortion
THD = sps.THD;
save('sps.mat','sps','-mat');
Everything will be in sps structure.

Hi Samitha,
I want only voltage harmonic magnitude Vs harmonic order to be tabulated from Simulink FFT Tool. Kindly explain how it could be done
did you find any solution
