Harmonic Assessment Based Adjusted Current Total Harmonic Distortion [PDF]
The Journal of Engineering, 2016 Power systems suffer from harmonic distortion and extra ohmic losses associated with them. Moreover, all harmonic frequencies are mostly assumed to have the same effect on the system losses. However, the frequency‐dependency of the resistances should be taken into account, so that the apparent power and the power factor have to ...

Nonlinearities of GaAlAs lasers - Harmonic distortion [PDF]
IEEE Journal of Quantum Electronics, 1980 Narrow stripe lasers ( 2-6 \mu m) and transverse junction lasers exhibit excellent linearity. The dependence of relative second-and third-harmonic distortion is investigated as a function of modulation frequency and modulation current. Relative second- and third-harmonic distortion of -50 and -70 dB is observed for an optical signal of 4 mW p-p ( f_{m}

Harmonic distortion in CMOS current mirrors [PDF]
ISCAS '98. Proceedings of the 1998 IEEE International Symposium on Circuits and Systems (Cat. No.98CH36187), 2002 One of the origins of harmonic distortion in CMOS current mirrors is the inevitable mismatch between the MOS transistors involved. In this paper we examine both single current mirrors and complementary class AB current mirrors and develop an analytical model for the mismatch induced harmonic distortion.

Harmonic distortion in public low-voltage grids Comparison of the situation in Colombia and Germany [PDF]
Ingeniería e Investigación, 2015 Current and voltage harmonic levels in LV grids depend not only on the harmonic emission of non-linear loads, but also on the characteristics of the grid and the voltage distortion of the upstream grid.

A harmonic distortion standard [PDF]
ICASSP '83. IEEE International Conference on Acoustics, Speech, and Signal Processing, 1983 All harmonic distortion analyzer instruments may not give the same reading when measuring a particular audio range signal. A design method is presented that can supply a signal with a precisely determined amount of harmonic distortion. Digital signal generation technique is used. Factors which determine the accuracy of the signal are examined.
