for a white noise the psd is flat i.e the distribution of energy over central freq is 1 and for gaussian noise as the name says the psd is normally distributed.

What do you mean by Gaussian noise?
Gaussian noise is similar to white noise, but it falls within a narrower range of frequencies. In communications, it is produced by the movement of electricity through the line. You see and hear that when you have your television on an empty channel. Within photos and videos, Gaussian noise is in the form of random patterns, and this is what makes things look slightly blurry.
What is the difference in light intensity between white and black?
Contrast Ratio
For a monitor the difference between the brightest white and the darkest black is called the?
contrast ratio
How can you tell the difference between a laser and a beam of white light?
A beam of white light is white. A laser is not; it's monochromatic (one specific frequency of light, therefore colored and not white).
What is difference between blank space and white space?
Blank space if not filled with anything and could be colorless, or any color. White space is filled with white but is definitely white but looks empty.
What is the difference between white Gaussian noise and additive white Gaussian noise?
A Gaussian noise is a type of statistical noise in which the amplitude of the noise follows that of a Gaussian distribustion whereas additive white Gaussian noise is a linear combination of a Gaussian noise and a white noise (white noise has a flat or constant power spectral density).

What is AWGN channel?
An AWGN channel adds white Gaussian noise to the signal that passes through it.
What is circular complex Additive White Gaussian Noise?
"Circular" means the variance of the real and imaginary parts are equal. "White" refers to the fact that the power spectral density of the noise is flat across the whole frequency spectrum. This means that its autocorrelation is a Dirac-delta at t=0 (so its covariance matrix will show noise powers on the diagonal elements and zeros elsewhere). "Gaussian" means the probability distribution of the amplitudes of the noise samples is Gaussian.
A communication channel with additive white gaussian noise has a bandwidth of 4kHz and SNR of 31dB. Its channel capacity is?
20kbps
What is the difference white noise and impulse noise?
Thermal noise occurs in all transmission media and all communication equipment, including passive devices. It arises from random electron motion and is characterized by a uniform distribution of energy over the frequency spectrum with a Gaussian distribution of levels. Noise. Impulse noise is noncontinuous, consisting of irregular pulses or noise "spikes" of short duration, broad spectral density, and relatively high amplitude.
Why thermal noise is called white noise?
Thermal noise occurs due to the motion of millions of electrons in a object. Due to the central limit theorem, the total effect can be modeled as a Gaussian distributed random variable with zero mean and N_0/2 variance.

What is audible matrix?
When you are between 2 difference pieces of appliances or electronics emitting a white noise and your brain tries to make sense or order out of it by creating words that were not actually there
Is there a difference between white and purple eggplant?
The main difference between white and purple eggplant is the color. On the inside, there is almost no difference in taste or texture between the two.
What is the difference between a white lion and a regular lion?
The main difference between a white lion and a brown lion is the colour. There are white tigewrs , but are there white lions also?
