Re: Oh Really??

OK, I see where you are coming from when you are talking about averaging.

I guess why I was confused about what you were saying is requirements are more than just a digital filter, it is a digital filter that has a higher resolution than the original quantization level (and the results are non re-quantized to the original level as with earlier oversampling DACs) so that you can actually represent sub LSB.

But in theory the analog filter is good enough then because it is essentialy like the digital filter but with infinite (or at least very large) bit depth so the same effect should be seen...
