Wedge and Rutledge : Wave Techniques for Noise Modeling and Measurement 2005

The noise wave approach is applied to analysis, modeling, and measurement applications. Methods are presented for the calculation of component and network noise wave correlation matrices. Embedding calculations, relations to twoport figures-of-merit, and transformations to traditional representations are discussed. Simple expressions are derived for MESFET and HEMT noise wave parameters based o...

Low-current Noise Measurement Techniques

The noise of a resistive sample is a measurable physical property. The noise signature can depend on such variables as the materials used in preparing a sample and the method used to prepare it. A versatile experimental technique is needed to measure these noise signatures, one which can be applied to any form of resistive structure. In addition, many samples with unique physical properties, su...

Image Noise: Detection, Measurement, and Removal Techniques

The report surveys the evolution of image denoising techniques from the perspectives of detection, measurement, and removal. Since noise detection and measurement are intrinsically the same, we focus on the discussion of noise measurement and noise removal techniques. For noise measurement approaches, we survey filter-based, block-based, and wavelet-based, as well as other important achievement...

Auditory modeling techniques for robust pitch extraction and noise reduction

A novel method for robust pitch extraction, based on the correlogram output of the Lyon’s cochlear model is described. The value of the autocorrelation lag for which the signals of the cochlear channels have the same periodicity can be computed thus tracking how the pitch of the input signal varies in the time domain. In the case of a stationary noise, a sort of ‘spectralsubtraction’ technique,...
