However, the above formulation assumes that your data are even. I would go further and try to pad your time data with zeros to next power of 2 (i.e., above is 2^10). Let me know if you have questions about doing that.Depending...

to estimate it from random samples using nufftn(). The range and overall shape of the estimate comes out right on, but it's very noisy, becaue the random samples aren't uniform and therefore aren't great for estimating Fourier Transform coefficients. And it takes major oversampling to ...
Open in MATLAB Online I think I am confused I how to get the Fourier transform of the time-domain signal. The tf gives me the num and den in laplace, then I am trying to get the tf into the time domain, and then plug in t values till 1800 seconds, then get the fft o...
Open in MATLAB Online Ran in: The signal has an extremely high level of broadband noise, and the recovered time domain signal reflects that. One option to deal with the broadband noise in the Fourier transform is to use the Savitzky-Golay filter (sgol...
