How to plot FFT in MATLAB by executing Vibration data recorded in Excel?

45 views (last 30 days)
I have several recorded vibration measurements in Exel files as Time vs. Acceleration. Now I need to plot Time Vs. Acc and FFT graphs for further analysis.
Thank in Advance for all put their comments and suggestions below!

Use the fft function. The documentation will tell you how best to implement it for your signal.
Note that the sampling intervals must be constant, so if they are not, first use the Signal Processing Toolbox resample function to interpolate them to a constant sampling interval. Then use the fft function to calculate the spectra.
