AD/DA変換におけるプレフィルタとポストフィルタの二段階設計

抄録

In the field of signal processing, AD/DA converter takes an important role for data compressing and circuits design. This paper proposes new design method of AD/DA system with pre-filter and post-filters for achieving small quantization noise effect. Both filters are designed to minimize noise and distortion toward original signal. The effectiveness is illustrated by numerical example.
