### Purpose

Phase spectrum of a signal

### Description

"Phase spectrum" calculates the phase spectrum

or

of the given signal where R denotes the real part of
the Fourier Transform of the input signal and I denotes the
corresponding imaginary part.
"Phase spectrum" performs an FFT (Fast Fourier Transform) for computing the phases.

The output is given in degrees as a function of the frequency.
