Answer 2

Autocorrelation function of awgn is described by Box, Jenkins, & Reinsel in 1994.

Explanation:

• The autocorrelation function (ACF) tells how data points in a time series are related, on average, to the preceding data points.
• It is also known as serial correlation in the discrete time case, it is the correlation of a signal having a delayed copy of itself as a function of delay.
• In simple words, it calculates or measures the self-similarity of the signal over different delay times.
• This function exhibits the harmonic structure of musical tones.
• It is described by Box, Jenkins, & Reinsel in 1994.
• The autocorrelation function of a white noise signal is the Dirac delta distribution.
