The Rice characteristic frequency f of a time history is
where y is the amplitude
It is useful for estimating the dominant frequency for signal which is fairly sinusoidal.
Here is a Matlab script: rice_frequency.m

Hello sir, I have searched the entire Internet but couldn’t find any introduction to the source of Rice frequency. Would it be convenient for you to explain the origin and development of Rice frequency?
I think I’ve found.Thanks.

The method can be extended to random vibration by using standard deviations rather than peak values.
