What is a white noise process give examples?

White Noise, by definition, works by defining parameters in which data is ensured to be random, unrelated, and have zero mean. White Noise can even be produced within the context of binary variables. For example, a sequence of 0's and 1's would be white if the sequence is statistically uncorrelated.

How do you show white noise in a process?

By definition, the random process X(t) is called white noise if SX(f) is constant for all frequencies. By convention, the constant is usually denoted by N02. The random process X(t) is called a white noise process if SX(f)=N02, for all f.

How do you explain white noise?

White noise refers to a noise that contains all frequencies across the spectrum of audible sound in equal measure. Because white noise spans multiple bands of sound, it is sometimes referred to as broadband noise. Anecdotally, people often liken white noise to the static that comes from an untuned radio or television.

What is a white noise process in time series?

A time series is white noise if the variables are independent and identically distributed with a mean of zero. This means that all variables have the same variance (sigma^2) and each value has a zero correlation with all other values in the series.
