What is Gaussian noise formula?

The random process X(t) is called a white Gaussian noise process if X(t) is a stationary Gaussian random process with zero mean, μX=0, and flat power spectral density, SX(f)=N02, for all f.

Is noise Always Gaussian?

Many real noise sources tend to look more or less Gaussian-ish. But Gaussian noise has a very strict mathematical definition. Real-world things, such as noise from wind and other sources, don't cause mathematical models.

Does noise follow Gaussian distribution?

When an electrical variation obeys a Gaussian distribution, such as in the case of thermal motion cited above, it is called Gaussian noise, or RANDOM NOISE. Other examples occur with some types of radio tubes or semi-conductors where the noise may be amplified to produce a noise generator.

Is white noise always Gaussian?

It is important to note that white noise is not always Gaussian noise. Gaussian noise means the probability density function of the noise has a Gaussian distribution, which basically defines the probability of the signal having a certain value.
