| Abstract(in English) | It is apt to be considered that sampling frequency determined the band width and the number of quantizing bits determined the dynamic range.But the one and the other are closely related.In digital signal processing the effect of finite word length must always be taken into considerration.In AD/DA conversion the effect of finite word length appears as the quantization noise.Recently a ΣΔ modulation type converter is taken special notice of,which concentrates quantization noise in the higher frequency area by setting a quantizer in the feedback loop.Here the 1 bit AD/DA conversion and signal processing of wide range acoustic signals with high speed sampling will be discussed. |
