white′ noise′ n. random noise with a uniform frequency spectrum over a wide range of frequencies. [1965–70] Random House Kernerman Webster's College Dictionary, © 2010 K Dictionaries Ltd. Copyright 2005, 1997, 1991 by Random House, Inc. All rights reserved. ...
a digital-analog converter and filter and outputs an analog white noise frequency spectrum, and the inverse of the frequency spectrum is a compensation function of the white noise in a frequency domain; step 3, the compensation function of the frequency domain is converted to a time domain; and...

White noise, on the other hand, covers all the frequencies, from low-frequency bass notes to high-frequency chimes. It effectively masks sound inconsistencies, helping you drift into a peaceful slumber. Natural occurrences like sprinkling rain or a gentle breeze rustling through trees can be consid...
White Noise It’s the most popular type of color noise. It contains all frequencies found in the spectrum of sounds you can hear in equal parts. It’s often called “broadband noise.” White noise uses a mix of sound frequencies to create a static-like sound. It can be intense and hig...
Can you produce a frequency spectrum for all frequencies at the same time? Answer: Noise in electrical circuits is typically the enemy, and any self-respecting circuit should output as little noise as possible. Nevertheless, there are cases where a well-characterized source of noise with no othe...
In most situations, the assumption that the noise introduced by the channel is white, which means that the noise received at any frequency is approximately the same, can justifiably be made. An example of zero-mean white Gaussian noise with a variance of σn2 = 0.25 is shown in Figure 3.3...
The authors extend earlier analysis and consider the reduction in white noise across the spectrum when a novel noise cancellation circuit is used. It is shown that at carrier to noise ratios below the threshold level, up to 6 dB reduction in the noise floor can be achieved in frequency modula...
Nearly all sound machines offer white noise, a sound made up of every frequency audible to the human ear. White noise balances each of these frequencies equally. Other “colors” of noise favor higher or lower frequencies over that balance. The two most common shades of sound to be included...
