How is the prediction-error filter computed? Let h be a causal prediction filter for prediction distance one. Let the input be $x_{k}$ where $x_{0}$ occurs at time zero. The desired output is the input advanced by one time unit; that is, the desired output is $z_{k}=x_{k+1}$, where $z_{0}=x_{1}$ occurs at time zero. Thus, the crosscorrelation is
