What are response phase lead and response frequency? Response frequency is the value of instantaneous frequency at the peak of the amplitude envelope and is a measure of the dominant frequency of the waveform contained within the envelope. The response phase is the dominant phase of the waveform. The response phase is independent of amplitude and is useful in measuring phase variations from energy lobe to energy lobe. Major reflections produce significant energy bursts on a seismic trace, and on the instantaneous-amplitude representation of the trace, the reflections are the local maxima. In other words, reflections occur in those parts of the envelope located between successive minima.
