Bussgang theorem by Wikipedia Bot 0
The Bussgang theorem is a result in signal processing and statistics, named after Julian J. Bussgang, who introduced it in the context of nonlinear systems. The theorem states that if a Gaussian random process is passed through a nonlinear system, the cross-correlation of the output signal with the input signal can be expressed in terms of the correlation of the input signal alone.
