The phrase "are not harmonic" is correct and usable in written English.
It can be used in contexts discussing music, mathematics, or any situation where harmony or compatibility is being evaluated.
Example: "The two melodies played together are not harmonic, creating a dissonant sound that is jarring to the listener."
Alternatives: "lack harmony" or "are disharmonious".
In order to determine the rate of ripples and of fast ripples that were not harmonics due to a non-sinusoidal ripple waveform, we used an unbiased method to identify HFA events of six or more cycles based on thresholding HFA cycles at five times the overall signal standard deviation and characterized them as ripples and fast ripples by their median interspike intervals (Fig. 5A and B).
In whispered and aspirated segments, where the vocal folds are not vibrating, harmonic components are also absent in the 0 to 1500 Hz frequency band.
In these cases, harmonic onsets are not separated in the harmonic signal as can be seen in Figure 11.
However, in these cases the approximating functions (mathcal{P}_{r}[f]) are not analytic but harmonic in a suitable meaning.
For this type of configuration, the spectra are mainly characterized by the presence of several dominant peaks (Rossiter modes) that are not in a harmonic relation but uniformly spaced at a distance equal to the fundamental frequency of the oscillation mechanism (aero-acoustic feedback loop).
Regarding the harmonic analysis, paired t-tests shown that the first four harmonics are not significant different (p ⩽ 0.05), and Pearson correlation studies retrieve that the 2nd 7th harmonics are correlated (p ⩽ 0.03).
The paper characterizes some classes of pseudo-differential operators for which there are (or there are not) non-constant bounded harmonic functions.
In musical context, IMD is often an undesired phenomenon, since IMD components generally fall at frequencies which are not in any simple harmonic relation to the original tones, making the resulting sound noisy and inharmonic.
Secondly, the amplitudes of the primary harmonics in a MFM signal are not equal and decrease as harmonic order increases.
