"frequency evolution" is a correct and usable phrase in written English.
You could use it to refer to the gradual alteration of sound frequency over time, as in the example sentence, "Archaeologists have observed patterns of frequency evolution in cave art remnants."
Figure 20 FPGA working frequency evolution.
Figure 9 represents the centroid frequency evolution with depth (time of flight).
Our aim here is to correctly model the frequency evolution of the seizure.
The whole 10 s window was used to model the frequency evolution of the seizure.
The Nakamura spectral ratio can reveal the predominant resonance frequency evolution rule of coal-rock mass after relieve-shot being discovered.
By dividing the binary representation in smaller regions, along horizontal -axis, we will be able to study the central frequency evolution with depth.
Equilibrium and periodic solutions are explored with respect to the blowing pressure, with focus on amplitude and frequency evolutions along the different solution branches, as well as "jumps" between periodic solution branches.
The signal-to-noise ratio R showed a time-frequency evolution similar to that observed by the spacecraft between 0830 and 1730 UT, at low latitudes more clearly in the D component, not affected by resonant phenomena.
Two different approaches were evaluated: (1) analysis of the structure frequencies evolution by means of the continuous wavelet transform and (2) analysis of the singularities generated in the high frequency response of the structure through the detail functions obtained via fast wavelet transform.
In this article, we considered a stochastic model of mutant-frequency evolution that can be used to infer the effective population size, selection coefficient, and mutation rates from temporal allele-frequency data using the method of maximum likelihood.
Linkage disequilibrium (LD) throughout the genome reflects the population history, the breeding system, and the pattern of geographic subdivision, whereas LD in each genomic region reflects the history of natural selection, gene conversion, mutation, and other forces that cause gene-frequency evolution (Slatkin 2008).
