Data analytics relation to digital signal processing

Hi Khurram! Thanks for reaching out. Data Analytics - think of it as combination of mathematical skills/quantitative methods and quantitative data, excluding any business concept. You don't need to understand precisely what Digital signal processing is about; it is enough to remember it involves computations and predictions about future behaviour of signal, using the available quantitative data (which is, again, about the signal). There's no business context here, however there is work with quantitative data, and the latter characterises Data Analytics. Hope this helps.
Best,
Martin
