Matlab code on How to fix the problem with this signal?

3 views (last 30 days)
Dear all.
I am trying to write a matlab code to help me do the following:
  • I have a signal obtained from a sensor, the signal represent the velocity of an object, well my goal was to obtain displasement (position signal) but the direct integration caused an error in the signal obtained (shown in Fig.01)
  • I would like to find a way how to make the signal straight without affecting the amplitude neither the frequency, I checked the values of Pk to Pk amplitude and it is correct.
  • I do not have the original velocity signal to make mat-operation on it, so I have with the position signal.
I appreciate your kind help

Use the detrend function —
F = openfig(websave('disppertime',''));
Ax = gca;
Kids = Ax.Children;
xv = Kids.XData;
yv = Kids.YData;
yvdt = detrend(yv, 1);
plot(xv, yvdt)
This will work for the main plot data.
