Definition of power spectrum in English:

power spectrum

noun

Physics

The distribution of the energy of a waveform among its different frequency components.
Example sentencesExamples
- The relative values of the different components in the Fourier power spectrum express the comparative contribution of those frequencies of variation to the total energy of the original function.
- We measured maximum frequency and minimum frequency of the fundamental harmonic of the call from spectrograms, and frequency of most energy from a power spectrum.
- The power spectrum emphasizes dominant frequencies of the signal whereas signal memory is emphasized by the autocorrelation.
- The spatial frequency and direction of any component in the power spectrum are given by the length and direction, respectively, of a vector from the origin to that point.
- This provided an average value of the power spectrum at the frequency of the oscillator.
