The Fourier amplitude spectrum FS(ω) is defined as the square root of the sum of the squares of the real and imaginary parts of F(ω) .
Read moreHow do you calculate spectrum?
Frequency spectrum of a signal is the range of frequencies contained by a signal. For example, a square wave is shown in Fig. 3.5A. It can be represented by a series of sine waves, S(t) = 4A/π sin(2πft) + 4A/3π sin(2π(3f)t) + 4A/5π sin(2π(5f)t + …)

The Fourier amplitude spectrum FS(ω) is defined as the square root of the sum of the squares of the real and imaginary parts of F(ω) .
Read moreWhat does amplitude mean in FFT?
The frequency axis is identical to that of the two-sided power spectrum. The amplitude of the FFT is related to the number of points in the time-domain signal .
Read moreWhat is an amplitude spectrum?
amplitude spectrum specifies the amplitude of signal components as a function of component . frequency . The phase spectrum specifies the phase of signal components as a function of. component frequency. This phase is measured with respect to a cosine reference.
