What are the spectral components of a signal?
In telecommunications, spectral component is any of the waves that range outside the interval of frequencies assigned to a signal. Any waveform can be disassembled into its spectral components by Fourier analysis or Fourier transformation.What are the components of spectral frequency?
Briefly, the frequency spectrum of any signal is composed of two parts, the magnitude and the phase.- Spectral analysis is the process of estimating the power spectrum (PS) of a signal from its time-domain representation. Spectral density characterizes the frequency content of a signal or a stochastic process.
