Nonlinear distortions and multisine signals. II. Minimizing the distortion

IEEE Transactions on Instrumentation and Measurement, 2000
For Pt. I see ibid. vol. 49, pp. 602-609, 2000. This paper examines the effects of nonlinear distortions on frequency response functions estimated using multisine test signals. The aim is to minimize the distortion introduced by the nonlinearity, for a given input power constraint.

Analyses of LED nonlinear distortions

IEEE Transactions on Electron Devices, 1978
This paper treats LED nonlinear distortions of differential gain (DG) and differential phase (DP) theoretically. Possible origins and numerical analyses are presented for Al/sub x/ Ga/sub 1-x/As LED's, considering various junction structure; double-heterostructure, single-heterostructure, and homostructure. It is shown that homostructure is superior to

Linear modeling in the presence of nonlinear distortions

IEEE Transactions on Instrumentation and Measurement, 2002
In this paper we set up a framework to deal with nonlinear distortions in a linear modelling framework. The nonlinear system is replaced by a linear system plus a noise source. The properties of this representation are given, and a measurement technique to extract the linear model and the noise variance is developed. Eventually the different aspects of

Nonlinear FM Distortion Equalizer

IEEE Transactions on Communications, 1978
A new approach to FM distortion equalization is suggested and a nonlinear equalizer operating in the baseband frequency range is presented. It is shown that, using analog multipliers and differentiators, a baseband equalizer can be designed which eliminates all types of distortion products.

An adaptive nonlinear prefilter for compensation of distortion in nonlinear systems

IEEE Transactions on Signal Processing, 1998
This article concerns the linearization of a nonlinear system by connecting a nonlinear Volterra prefilter tandemly with the nonlinear system and by adaptively adjusting the coefficients of the prefilter. "A nonlinear filtered-x LMS algorithm" for updating the coefficients of a nonlinear prefilter, as proposed, is shown to be viewed as an extension of ...

Nonlinear independent component analysis with minimal nonlinear distortion

Proceedings of the 24th international conference on Machine learning, 2007
Nonlinear ICA may not result in nonlinear blind source separation, since solutions to nonlinear ICA are highly non-unique. In practice, the nonlinearity in the data generation procedure is usually not strong. Thus it is reasonable to select the solution with the mixing procedure close to linear. In this paper we propose to solve nonlinear ICA with the "

Compensating out-of-band nonlinear distortions

2010 IEEE Instrumentation & Measurement Technology Conference Proceedings, 2010
In this paper a method is proposed to compensate for the nonlinear distortions present in the input signal of a DUT which results in a source-pull free level of the output nonlinear distortions. This allows to determine an accurate adjacent co-channel power ratio (ACPR).

Nonlinear Distortion in Modern Hearing Aids

Journal of Speech and Hearing Research, 1967
Nonlinear distortion was investigated in 367 new hearing aids. Among the first group of instruments examined, the level of harmonic distortion present at 500, 700, and 900 Hz was studied, together with the frequency and extent of maximum distortion. Ear-level instruments generally yielded lower distortion values than did body types.
