In discrete sense, the white noise signal … Webwhere denotes the expected value of (a function of the random variables ).. In other words, the autocorrelation function of white noise is an impulse at lag 0. Since the power spectral density is the Fourier transform of the autocorrelation function, the PSD of white noise is a constant. Therefore, all frequency components are equally present--hence the name …
WebA white noise signal has a flat power spectral density, or equal power per unit frequency.
