What information do we get from magnitude and phase representation?

The magnitude tells you the strength of the frequency components relative to other components. The phase tells you how all the frequency components align in time. Plot the magnitude and the phase components of the frequency spectrum of the signal.

What do magnitude and phase plots in a spectrum tell us?

Magnitude of the analytic signal gives the magnitude spectrum, and phase angle of the analytic signal gives phase spectrum. From these spectrums, features, such as standard deviation of amplitude, standard deviation of phase, and signal energy, are extracted.

What is magnitude and phase spectrum?

The exponential Fourier series representation of a periodic function x(t) has amplitude coefficients Cn which are complex and can be represented by magnitude and phase. Hence, we can plot the amplitude spectrum (|Cn| versus ω) and the phase spectrum (∠Cnversusω).

What does phase spectrum tell us?

By the common words, the phase spectrum shows the phase shifts between signals with different frequencies. The very simple example is the chromatic dispersion. Assume the signal has definite phase shifts at the input in some volume with dispersive medium.
