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 ...

Analysis of Harmonic Distortion in the Colpitts Oscillator

2006 13th IEEE International Conference on Electronics, Circuits and Systems, 2006
In 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 ...

Bounded distortion harmonic shape interpolation

ACM Transactions on Graphics, 2016
Planar shape interpolation is a classic problem in computer graphics. We present a novel shape interpolation method that blends C ∞ planar harmonic mappings represented in closed-form. The intermediate mappings in the blending are guaranteed to be locally injective C ∞

Bounded distortion harmonic mappings in the plane

ACM Transactions on Graphics, 2015
We present a framework for the computation of harmonic and conformal mappings in the plane with mathematical guarantees that the computed mappings are C ∞ , locally injective and satisfy strict bounds on the conformal and isometric distortion.

Removing harmonic distortion in tiled screens

2015 Asia-Pacific Signal and Information Processing Association Annual Summit and Conference (APSIPA), 2015
When 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 ...

Elimination of harmonic distortion in Vibroseis data

Geophysics, 1994
Abstract 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 ...

Harmonic Bandpass Distortion of a Chebyshev Nonlinearity

IEEE Transactions on Communications, 1976
Harmonic 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.

Decomposition of Harmonically Distorted Chirps into their Harmonic Components

2009 IEEE 13th Digital Signal Processing Workshop and 5th IEEE Signal Processing Education Workshop, 2009
Two 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 ...

Harmonic injection method: a novel method for harmonic distortion analysis

ISCAS 2001. The 2001 IEEE International Symposium on Circuits and Systems (Cat. No.01CH37196), 2002
In this paper we propose a novel method for analysing harmonic components of the signals produced by nonlinear dynamical systems. The proposed method, unlike numerical analysis method, gives symbolic answers that allow us to interpret the operation of the analysed systems more insightfully. To demonstrate the accuracy and the flexibility of our method,
