Multi-parameter estimation of harmonics based on quaternion matrix
The safe fruit may be called the apple, because "the apple" also is the safe harmonics, moreover is the safe fruit's harmonics, therefore delivers the apple.
On relationship of ionization probability and radiation harmonics of hydrogen atom in laser field;
Vehicle group 110 kV transformer connecting system example analysis of comprehensive treatment scheme of higher order current harmonics
In the past, such harmonic sources were not very widely used, and harmonics were often effectively mitigated through the use of the grounded wye-delta transformer connection.
Based on the limitation of harmonics content in China's power systems, the influence of sampling frequency for alternating signals on measurement of harmonic power is discussed.
These methods can't be used not only to analyze the non integral order harmonics, but to distinguish the eccentricity and the first harmonic, and contain the lager nonlinear error.
These are called spherical harmonics.
An improved method without PLL on harmonics detection
the other is the cogging harmonics existed in the BEMF waveform.
It proves that it is feasible to apply the wavelet transformation to the detection of non-integer harmonics, thus, an effective means is provided for accurate detection of harmonics.
Considering azimuthal space harmonics, the finite size vane model is suggested for vane-loaded helical slow-wave structures in this paper.
Comparing with the FFT and the amplitude measure arithmetic, the novel method can avoid the spectrum leakage and fence effect in ideal extent and improve the precision of harmonics measurement.
You know them as harmonics or overtones.
The harmonics damages and disposing solutions of common DC bus frequency conversion drive system
The song I've written for this tuning makes deliberate use of this note, with a cascading harmonics effect.
Moreover, since the all-phase preprocessing can suppress the individual harmonics' spectral interference on the fundamental wave, the accuracy is greatly enhanced.

In addition, the thesis analyzes the influence of the filter structure and parameters on the output DC voltage ripple and the shape of phase currents, as well as harmonics of phase currents.
Some of the more common sources of these harmonics are:
It has a power factor of near 1, and decreases the harmonics interference to the lowest level.
Of or relating to harmonics.
The violinist had the technical skill to execute the cadenza, with its double stops and harmonics, with brilliance.
It is found that there exist odd harmonics, even harmonics and semi-integer harmonics due to the coherent interaction between two colors.
To measure phase accurately in the presence of harmonics for both noisy input signals, a technique based adaptive bandpass filter (ABF) and the method of interchanging signal channel is presented.
The features of the new method are simple main circuit, without big transformer and inductor, high power factor and low harmonics, easy to start and by pass operation.
