>>13456306if you are really wanting to get deep understanding of what you're doing at DSP you should take a complex analysis course before (specially about the Z transform which is also usefull on digital control stuff).
Otherwise you can still make it but you will have to accept some ideas as given without question. You can always go back on the complex analysis later tho.
Said that, any Complex numbers appendix from a Linear algebra book should be enough for you at the moment.
