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 .

How do you plot amplitude 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 is an amplitude spectrum plot?

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.
