convert time to frequency domain
Show older comments
Hi , I'm very new to MATLab. I have a time versus amplitude data file from an oscilloscope. I want to convert the time to frequency domain, and get a plot of the frequency vs normalised frequency graph. Could anyone help me with this? Thanking you in advance.

Hi,
You would need to read/import your time domain data in MATLAB and then perform Fourier Transform (undertand from the good source referred by Kalyan) with MATLAB's fft() (https://www.mathworks.com/help/matlab/ref/fft.html).
It is quite straightforward once you get your data into MATLAB workspace. Find out the value of a sampling frequency or sampling time from your colleccted data from oscilloscope to generate the frequency vector.
Good luck.
