To reduce the dynamic range of the difference signal d(n) = x(n) – $\hat{x}(n)$, thus a predictor of order p has the form?

$\hat{x}(n)=\sum_{k=0}^pa_k x(n+k)$

$\hat{x}(n)=\sum_{k=1}^pa_k x(n+k)$

$\hat{x}(n)=\sum_{k=1}^pa_k x(n-k)$

$\hat{x}(n)=\sum_{k=0}^pa_k x(n+k)$

$\hat{x}(n)=\sum_{k=0}^pa_k x(n-k)$
