The phrase "a mix of frequency" is correct and usable in written English.
It can be used when discussing a combination of different frequencies, such as in music, sound waves, or data analysis.
Example: "The audio track features a mix of frequency that enhances the listening experience."
Alternatives: "a combination of frequencies" or "a blend of frequencies".
The test presents a mix of frequency-banded words as well as phonologically-possible nonwords.
Due on stream early in May, they were chosen to reflect a mix of print frequency, geographic spread and the different kinds of localised markets.
Our results suggest that even small changes in SAH can have strong effects on survival during larval and juvenile phases, although the patterns of selective mortality may reflect a complex mix of frequency-independent and frequency-dependent selection.
The standard US imaging had been improved by CPI (combined pulsed imaging), a sophisticated algorithm based on a mix of high and low frequencies that improves B-mode penetration and resolution.
The dubstep track Scary Monsters And Nice Sprites by Skrillex, which has a mix of very high and very low frequencies, was chosen to see whether electronic music could be an effective repellent.
Secretary Clinton promises to release spectrum warehoused by the federal government itself and to support a mix of licensed, unlicensed, and shared new frequencies that will accelerate nascent 5G applications, including the internet of things and autonomous vehicles, as well as increasingly high-definition video.
Thus, approximately half of the units showed frequency specificity of forward suppression in all conditions, and half of the units (16 units, 47%) showed a mix of effects, with some probe tone frequencies resulting in a significant bias of suppression towards them and others not.
The other populations, sampled at higher altitudes, consisted of a mix of A and B patterns in various frequencies with one or several individuals representing the D, E or F patterns.
Selective mortality of larval and juvenile fish is likely to be a mix of both 'soft' selection (i.e. frequency-dependent selection in which selective mortality is substitutable with nonselective, background mortality) and 'hard' selection (i.e. frequency-independent selection which generates survival variation in addition to any background mortality; Wallace 1975).
