I read through the paper posted before in the meantime (http://www.lavryengineering.com/docu...ing_Theory.pdf )
Is there any more (hopefully easy to understand) information about how these reconstruction filters work in practice? The paper comes close around page 18, where it is shown how at least the right half of a sinc function can be produced by some circuit.
I'm missing the left part of the sinc function because based on the explanation it is need as well to recreate the original wave-form.
I obviously never cared about how DA converters work, based on the paper I now think of thousands of of sinc-producing circuits which all add up to the final waveform.
Probably this is not how it works in practice but this a missing link for me now to agree that Nyquist theorem and good circuits is all that we need.
