Hello everyone,
I have a beginners question about 1D interpolation of a signal. I have a system which is supposed to be sampled at 65 Hz but we found that the sampling rate is not constant and varies between 55-65 Hz. For further analysis I want to interpolate the data to have a signal with constant intervals between the data points. I used the following code but it seems not appropriate as it does not work properly.
y=signal(1,1).L1.Q(1:2982,1); %this is an example signal
ly=length(y);x=0:ly-1;lx=length(x);li=ly\lx;xi=0:li:lx;yi=interp1(x,y,xi,'cubic');plot(x,y,'o',xi,yi)
Could someone show me how to interpolate this signal so I get a signal with a constant sampling rate?
Thank you very much.
