He analyzed recordings of 81 different birds, measuring the difference in frequency between each note and the next and looking for the same intervals used in diatonic, pentatonic, and chromatic scales.
Therefore, we measured discrimination thresholds for vibrations that either (1) had equal amplitude, such that rms velocity differed in proportion to the difference in frequency, or (2) had matched rms velocity (the vibrations differed in amplitude by the same proportion as they differed in frequency, but the higher frequency vibration had the smaller amplitude).
He chose the difference in frequency between the two beams so that it would match the difference in energy required to excite electrons in the potassium atoms by a specific amount, known as a Raman transition.
Then, taking advantage of the difference in frequency domain, MP-MIMO signal and LFM-MIMO signal are discriminated.
The difference in frequency resolution can be clearly seen in the narrower bands at lower frequencies and wider bands at higher frequencies.
The difference in frequency of DQA1*05 and DQB1*02 between confirmed patients and controls was statistically significant (P = 0.001 and P = 0.000, respectively), while it was not significant for DQB1*03 02 allele (P = 0.203; Table 5).
If so, it is likely that patients with myfascial TMD would have been affected more and in that case the difference in frequency would be even greater than found in the current study.
The difference in frequency resolution of 7.8 and 31.25 Hz above and below the threshold value of 1054 Hz, respectively, is illustrated by the different track widths of the resolved components.
The boundary between the low and the high frequency pathways was set to 1054 Hz (between C6 and C6#) where the difference in frequency between successive semitones starts to exceed the HF resolution.
The Empirical Transfer Function (ETF) was constructed as the difference in frequency spectra between the observed and synthetic ground motions, using the stochastic point source approach for the Taipei basin (Huang et al. 2017).
The difference in frequency (offset) between the first null (the point where the beat frequency being locked) from the reference frequency is given by Delta f= frac{1}{2 tau_{1}} (9) Fig. 8 Error signal as function of beat frequency.
