Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
The distribution of the energy of a waveform among its different frequency components.
- ‘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.’
- ‘This provided an average value of the power spectrum at the frequency of the oscillator.’
- ‘The power spectrum emphasizes dominant frequencies of the signal whereas signal memory is emphasized by the autocorrelation.’
- ‘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 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.’
