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.
