Since noise is random, a time function or time plot is not particularly useful. It is more common to discuss other properties of noise such as its probability distribution, its variance, or its frequency characteristics as described in Chapter 2. Although noise can take on a variety of differe...
These characteristics of switching paths depend on presence/absence of noise, its pathway of application (additive/multiplicative), and symmetry (odd/even) of the anharmonic potential. The dependence on the type of SF used, however, has been found to be not much significant unless the exclusive...
It has been known that short-time auditory stimulation can contribute to the improvement of the balancing ability of the human body. The present study aims to explore the effects of white Gaussian noise (WGN) of different intensities and frequencies on d
Several new methods and improvements have been proposed to address the mode mixing issue of EMD algorithm. One of these approaches is the ensemble empirical mode decomposition (EEMD). EEMD adds white Gaussian noise to the signal and performs decomposition of the original signal over an ensemble of...
Although it has more structure than an image of white noise, and perhaps more than the image drawn from the spectral model (Fig. 9.3), the result still does not look very much like a photographic image! Sign in to download full-size image FIGURE 9.6. A sample image drawn from the ...
The equations derived are solved for the case of third-order filters. Experimental and theoretical characteristics are given for the case of a noise generator using a third-order filter.doi:10.1080/00207176808905702SUTCLIFFE, H.TOMLINSON, G. H....
Denoising an image with additive white Gaussian noise (AWGN) is a challenging process. Parameters such as noise mean and variance provide noise characteristics of AWGN. This paper compares three different algorithm for noise estimations; ant colony optimization, fuzzy logic, and region merging. It ...
3)Gauss white noise高斯白噪声 1.Two methods,traditional Fourier analysis and wavelet packet transform,are presented for the characteristics of periodical narrow band interference and Gauss white noise in partial discharge to eliminate the two kinds of interferences.通过对周期性窄带干扰和高斯白噪声两种典...
The first order and second order bistable Duffing oscillator are selected as typical models for analyzing the stochastic characteristics of double-well nonlinear oscillators excited by sinusoidal force and Gaussian white noise. By employing cyclostationary Gaussian analysis, two solution modes of the almost...
noise degradation types is distinct and they are easier to manage when considered separately. Nevertheless, the Gaussian noise, through its masking effect, diminishes the accuracy of impulse detection methods, and in the following processing stage the remaining noise, which characteristics is generally ...
