I want to obtain Power spectrum of the Voltage Timeseries of Vela Pulsar data given in picture below :thinking: [image] How should i implement FFTW ?

How to find the DFT of a time series using FFTW: using FFTW: fft, fftshift, fftfreq data = ... # your data here fs = ... # specify sampling frequency here # frequencies where the DFT is evaluated: f_range = fftshift(fftfreq(data, fs)) # DFT of data data_f = fftshift(fft(data)) Using fftshift is…
