OVER-SAMPLING A/D, D/A CONVERTER

摘要

Hardware for an over-sampling A/D, D/A converter capable of operating under either software handling a first method having a fixed over-sampling ratio or software handling a second method having a variable over-sampling ratio, wherein a value N3 written in a pseudo division ratio register (11) via a user interface and a value N4 written in a pseudo over-sampling ratio register (21) are converted into a division ratio N1 by a conversion circuit (12) and written in a division ratio register (10).
