The king of all upsampling/oversampling questions...

[rfbrw]

that in signal theory terms oversampling does not necessitate re-quantisation,

I think you will find that it is pretty much unavoidable, using standard DSP parts.

rfbrw,

can you enlighten me on the "unavoidable" part. I don't doubt it, but as my books are not very practically oriented towards any dsp chip, they don't really cover this well.

A pointer somewhere? I probably need to get another more practise oriented book 🙂

cheers,
