  • Abstract
    Several definitions of `time-varying¿, `short-time¿ and `instantaneous¿ spectra exist. The paper relates these to the time-frequency energy distribution of a signal and to the time-varying power spectrum of a non-stationary random process. The treatment emphasizes physical interpretation, rather than mathematical rigour.
