Answer:A
If ak is the filter coefficient and a ̅k represents the quantized coefficient with Δak as the quantization error, then which of the following equation is true?
A. a ̅k = ak. Δak B. a ̅k = ak/Δak C. a ̅k = ak + Δak D. None of the mentioned
Explanation: The quantized coefficient a ̅k can be related to the un-quantized coefficient ak by the relation
