The phrase "frequency difference" is correct and can be used in written English.
For example, "The frequency difference between the two waveforms was very small."
Adaptation of the frequency difference was based on performance on different trials only.
Fisher's exact test was performed to test the frequency difference of immunocytochemistry staining (positive vs. negative) between different cells groups.
As crack depth increases frequency difference increases.
The frequency difference is then measured by a frequency counter.
b, Allele frequency of 45 Asian-specific insertions (≥0.3 allele frequency difference; ≤0.5 non-Asian allele frequency).
This result was consistent with previous studies which revealed the sensitivity of the frequency difference in the left hemisphere.
This frequency difference decreased to ∼1 ppm by one iteration of trap tuning.
We engineer a precise reference of the frequency difference through double photoassociation spectroscopy (PAS).
For the adiabatic acceleration (deceleration) of atoms, we linearly chirp (≈2 kHz ms−1) the frequency difference δν(t) over 60 ms.
The atom acceleration and positioning is controlled by the frequency difference δν(t)=ν2 t)−ν1 of the lattice lasers, as outlined in Fig. 1a,b.
(b) By tuning the frequency difference δν(t)=ν2−ν1 of the lattice lasers, the atoms are transported into a HC-PCF.
