Fix fft normalization #88

Closed r-pascua closed 4 years ago

r-pascua commented 4 years ago

This PR fixes the normalization of the FFT data in plot.labeled_waterfall and the functions that wrap it (currently just plot.fourier_transform_waterfalls). Previously, the FFT data only used the shifted output from np.fft.fft; now, the data is scaled by the resolution of the axis that the transform is performed over, in order to ensure correct units of transformed data.
