Instantaneous frequency is defined as the sinusoid frequency in a short window that fits the seismic trace around the corresponding time. From: Sustainable Geoscience for Natural Gas Subsurface Systems, 2022.

What is instantaneous frequency of FM signal?
The instantaneous frequency of an FM wave with carrier frequency ωc for a baseband message m(t) is ω(t) = ωc + kωm(t) (2) 8-1 Page 4 ✬ ✫ ✩ ✪ FM Signal Definition (cont.)
What is instantaneous amplitude?
peak amplitude (often shortened to simply ``amplitude''): the nonnegative value of the waveform's peak. instantaneous amplitude: the value of (either positive or negative) at any time .
How are instantaneous phase and frequency related?
1 Instantaneous magnitude and phase. holds for a sinusoidal function. The angular frequency ω or for the frequency creates the sensation of pitch by hearing the sound of the wave. The pitch goes higher as the frequency increases; the sensation of pitch is in proportion to the frequency on the logarithmic scale.
How do you find instantaneous frequency in Matlab?
ifq = instfreq( x , fs ) estimates the instantaneous frequency of a signal, x , sampled at a rate fs . If x is a matrix, then the function estimates the instantaneous frequency independently for each column and returns the result in the corresponding column of ifq .
