It's packed in the conventional FFT format. Here is a function in numpy (the
successor to Numeric, which I assume that you are using) that generates the
corresponding frequencies in the same packed format:
Dear all,
I need to do a FFT on an array of 20k real values. Origin of the sampled
data is a sinus wave with light harmonics.
The goal is an frequency spectrum with the magnitudes of the first 50.
harmonics.
I addressed python like:
test_arr = src_data_dict[ channel ][0:19599]
