Abstract
A new approach is presented which allows proper spectral measurements of time-nonstationary signals. The power spectrum is defined on the basis of ensemble averages and therefore contains a time variation when the signals are nonstationary. It is shown that a spectrum analyzer can be designed which measures these time-varying spectra in a nearly optimum manner. Design equations are given and practical considerations are discussed.
