First, I'm not an engineer, so I don't know this topic very well. Anyway, we were covering Fourier Transforms in one of my analytical methods class (chem major; NMR was the topic) and the phrase "discrete signal processing" came up. In our particular case, we collect individual points on the freq domain, do a FT and that gives us our data. my question was: how does this related to continuous signal processing? it seems like the only way to get a continuous sample is to take an infinite number of data points- which is impossible, right?
