good video very helpfull

I have to use the comparator operational amplifier for keep steepness origin. DA-AD or DA-ASP-AD schemes. Never go for algorithmical re-computing provided by many software or hardware. Why? Steepness is the secret of nature.

thank you very much

how does multi-channel-sampling work if you say we cannot reconstruct a signal with aliased? as far i know, you can use multiple aliased signals and put them together and you have a aliasing free signal. Could you explain this?
