Analysis of Harmonic Distortion in the Colpitts Oscillator
2006 13th IEEE International Conference on Electronics, Circuits and Systems, 2006In this communication a simple technique based on the phasor's method is presented in order to analytically deal with nearly sinusoidal oscillator constraints. Unlike other methods, more complex from a computational point of view, such as Volterra series and Poincare's perturbation, we are able to set the main linearity performance of a weakly ...

Impacts of Transformer Loading on the Harmonic Distortion Created by GIC Flows
IEEE transactions on industry applicationsGeomagnetically induced currents (GICs) are currents dominated by dc components that flow through grounding circuits into power systems. These currents are typically initiated by geomagnetic disturbances, and flow into power systems through power ...

Integral function method for determination of nonlinear harmonic distortion
Solid-State Electronics, 2004 The analysis of harmonic distortion is of prime importance for the analog and mixed integrated circuits. Recently we presented a new integral function method (IFM), based on a completely new principle, which allows the calculation of harmonic distortion ...

Elimination of harmonic distortion in Vibroseis data
Geophysics, 1994Abstract We present a new approach to eliminate the harmonic distortion in vibroseis data. This technique is based on the definition of the sweep for the case where the instantaneous frequency varies linearly with time. The method requires no more than the computation of a purely deterministic phase-shift filter that has the phase ...

Removing harmonic distortion in tiled screens
2015 Asia-Pacific Signal and Information Processing Association Annual Summit and Conference (APSIPA), 2015When producing halftones with the screening technique, tiling is generally used to construct a screen of appropriate size with screens of small fixed size. Regular tiling and random tiling are two common tiling schemes used nowadays. The former scheme produces periodic screens which introduce harmonic distortion to the screening outputs while the ...

Harmonic Bandpass Distortion of a Chebyshev Nonlinearity
IEEE Transactions on Communications, 1976Harmonic distortion imparted to the sidebands of an amplitude-modulated carrier by a system described by a Chebyshev series is evaluated. Sideband distortion increases with modulation depth but decreases with low carrier level, when even-harmonic contributions disappear.

Harmonic distortion and unbalance analysis in multi-inverter photovoltaic systems
International Symposium on Power Electronics, Electrical Drives, Automation and Motion, 2018The growing penetration of distributed generation connected to the grid by power electronics converters can adversely affect the power quality. The capability of the system to host large harmonic distortions and unbalance in three-phase systems may be an

Decomposition of Harmonically Distorted Chirps into their Harmonic Components
2009 IEEE 13th Digital Signal Processing Workshop and 5th IEEE Signal Processing Education Workshop, 2009Two techniques to isolate the harmonic components of non-linear harmonically distorted chirps are presented. Harmonically distorted chirps occur among other fields in the Vibroseis technique in seismic exploration. The harmonic components are theoretically and practically important as their spectral ratios to the fundamental component are used for ...
