What is DC level?
DC Level of a Signal. You can use DC measurements to define the value of a static or slowly varying signal. DC measurements can be both positive and negative. The DC value usually is constant within a specific time window.
What is zero mean Gaussian noise?
Gaussian white noise (GWN) is a stationary and ergodic random process with zero mean that is defined by the following fundamental property: any two values of GWN are statis- tically independent now matter how close they are in time.
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.
What is variance of Gaussian noise?
For Gaussian noise, this implies that the filtered white noise can be represented by a sequence of independent, zero-mean, Gaussian random variables with variance of σ2 = No W. Note that the variance of the samples and the rate at which they are taken are related by σ2 = Nofs/2.
