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?(a) \(\hat{x}(n)=\sum_{k=1}^pa_k x(n+k)\)(b) \(\hat{x}(n)=\sum_{k=1}^pa_k x(n-k)\)(c) \(\hat{x}(n)=\sum_{k=0}^pa_k x(n+k)\)(d) \(\hat{x}(n)=\sum_{k=0}^pa_k x(n-k)\)This question was addressed to me in an international level competition.My enquiry is from Oversampling A/D Converters in section Sampling and Reconstruction of Signals of Digital Signal Processing |
