Over-sampling A/D, D/A converter |
摘要 |
The hardware of an over-sampling A/D and D/A converter is provided, which hardware is capable of being operated with either kind of software: one corresponding to a first method in which the over-sampling ratio is fixed and the other corresponding to a second method in which the over-sampling ratio is variable. The value N3 written on the pseudo-frequency-dividing-ratio-register 11 and the value N4 written on the pseudo-over-sampling-ratio-register 21 are converted through a user interface into the frequency dividing ratio N1 by the conversion circuit 12 and the converted result is written in the frequency-dividing-ratio-register 10.
