Hi all,
I am trying to plot frequency response for the attached data. I can plot its time domain, However I am not able to plot the frequency response. Can anyone help please.
Regards

There is only one column of data, that I assume are the independent variable. You cannot plot its frequency response without an associated time vector (vector of sampling instants). This is important with respect to knowing if the sampling intervals are constant (they can be resampled to constnt samplilng intervals if not), since that is required for all signal processing applications, including the Fourier transform. The time vector is required in order to calculate the frequency vector (independent variable) in the fft plot.
