What is amplitude spectrum in Fourier transform?

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).

What is the 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.

How do you find the amplitude spectrum of a signal?

The shape of the amplitude spectrum is determined by the function sin( f ) f π τ π τ . the single rectangular pulse of width τ contains all frequencies between 0 and ∞. the relative amplitudes (ignoring the overall amplitude factor) of these frequencies is given by the function sin( f ) f π τ π τ .
