Not really, since you can generate signals that
not always can be sampled (if...

Well, actually "bis" is latin... :-) and means something
like "twice", or maybe "second try".

You can see it from a different point of view.

Hi,
I have a, maybe stupid, question about decimation and interpolation.
Let's say we have a signal sampled at 20KHz, so with an useful
bandwidth of 10KHz.
This is ideally low passed at 5KHz...Re: What is the advantage on high-sampling rate ?
