The phrase "as base frequency" is correct and usable in written English.
It can be used in contexts related to audio, signal processing, or any field where frequency is a relevant parameter.
Example: "The system operates optimally when set to a frequency of 440 Hz, which is recognized as base frequency for tuning musical instruments."
Alternatives: "as fundamental frequency" or "as reference frequency".
Parameters such as base frequencies, numbers of substitution types, proportion of invariable sites, and Gamma distribution shape were optimized using Modeltest3.7 [37] with the Akaike Information Criterion AICC).
Parameters such as base frequencies, substitution rate frequencies, among site rate variation, and invariant sites (I) were all estimated on the ML phylogeny using maximum likelihood methods under the GTR+I+Γ model [ 28- 30] as implemented in PAUP*.
MRBAYES 3.1 [ 46] was run with default settings (unless otherwise specified) using the basic parameters determined by MODELTEST, while allowing for the estimation of model-specific parameters such as base frequencies or gamma shape [p. 56 in ref [ 47]].
To use hierarchical clustering to optimise partitioning schemes, molecular evolutionary parameters (such as base frequencies and rates of molecular evolution) are first estimated for each initial data block, and data blocks are then combined based on the similarity of their parameter estimates.
Note that, as for sinusoidal variable at base frequency, the phase calculated through (14) is a fixed vector in the complex plane.
First, we assessed how prosodic realizations vary with speech rate and examined phrase command magnitudes, the number of phrase commands as well as the base frequency, accent command amplitudes, and the timing of accent command with respects to the underlying syllables and their nuclear vowels.
Figure 4 represents the read depth coverage along each position of the predicted disomic, trisomic and tetrasomic chromosomes of the Y strain, as well as the base frequency distribution between the heterozygous SNP positions.
As M ODELTEST 3.7 [ 56] identified the HKY model [ 57] as being most suitable for the COI data, we specified a transition/transversion ratio of 5.54 as determined in M EGA 4 [ 58], as well as empirical base frequencies.
If leaked CPU-Z images found on www.hkepc.com by Wccftech are true, it will be called the Threadripper 2990X and appears to sport a 3,4GHz base frequency as well as 64MB L3 cache.
In this paper, a simple and quantitative method is proposed to analyze the system parameters, such as waveform, power, base frequency, measured field and sampling time.
