Signals and Filters 101
I just need to learn the basic nuts and bolts of signals without having to go in depth into the math of deriving the Fourier Transform or signal design etc. Is that a possibility, and what is a good resource for this?


Sorry, I don't think it works this way. Without a proper understanding of the fundamentals, it's unlikely what you will every get useful results of your analysis. Check https://ccrma.stanford.edu/~jos/filters/ or http://www.dspguide.com/ for starters. This is good too, if you are up for it https://ocw.mit.edu/resources/res-6-007-signals-and-systems-spring-2011/introduction/
