Translations:Instantaneous attributes - book/29/en

To compute these response attributes, it is necessary to locate envelope-amplitude minima and maxima, to compute instantaneous phase lead and instantaneous frequency at the maxima, and to assign the resulting phase-lead and frequency values to all time samples located between two adjacent amplitude minima. As a result, both response phase lead and response frequency appear in the form of blocky traces, thereby showing phase lead and frequency in a physically more robust and meaningful manner than is the case for depiction of the instantaneous-phase-lead and instantaneous-frequency variables. On the other hand, the response attributes are not a measure of phase lead and frequency information at times other than at the envelope maxima.
