Instantaneous Amplitude, Phase and Frequency

Here is a link to a good discussion on this with MATLAB code.

Here is another place with a good discussion on doing a phase shift.
The Hilbert transform is fft ---> phase shift ---> ifft.
Doing fft and ifft are easy in numpy, and a phase shift is just multiplying each term in the signal by exp(j*p), where j is the imaginary unit, and p is the desired phase shift.

Project Results!

This is the raw data
This is the data after subtracting the reference signal
This is the data after each row has been differenced
This density function represents the sum of each column of the previous image
This is the result of using a five point smoothing function on the previous data
