Answer:
shows the phase shifts between signals with different frequencies.
Explanation:
Amplitude and phase, for a given frequency and given signal, can be calculated from Fourier transform. ... By the common words, the phase spectrum shows the phase shifts between signals with different frequencies. The very simple example is the chromatic dispersion.
