This is a pretty basic question. I’m trying to use SciPy/NumPy to perform fft on voltage vs. time data from an oscilloscope. I am completely lost when it comes to passing the data to scipy for fft processing. I have the data as two lists (x and y values) and obviously can zip the lists to tuple. I am unsure what to do though. I can’t seem to find much documentation. Apologies if this has been asked before, I could not locate a relevant question.

To sum up: If a person has x and y data stored in two lists or stored in a tuple, how do they perform FFT on these data?

    The documentation can be found at http://docs.scipy.org/doc/scipy/reference/generated/scipy.fftpack.fft.html

    I am not sure why you want to pass time; surely it is implicit in the sequence of voltage measurements?

    In general,

    import numpy as np
import scipy.fftpack

data = np.arange(0.0, 12.8, 0.1)
fft = scipy.fftpack.fft(data)
