I am would like to perform 45 degree phase rotation for a recorded signal.
I know I can achieve 90 degree phase rotation using hilbert transform. but how can I achieve phase rotation of 45 degrees?
I searched a in the internet, I can find examples for basic signals with the function. But, I could not find for recorded signal using matlab.
The figure below shows two signals u and w. the second plot can be obtained be plotting u vs w.
The figure below is the 45 degree phase rotated for u and w and it looks like
I have attached a sample signal similar to the plot. In my case the two signals are z1 and z2.
How can I achieve 45 degree phase rotation?
