How much of the time domain signal? You can't look into the future, and you don't want to be storing everything you've ever received so far. So \mathcal{F}\{R\}(f_1) = ?

I've been puzzling how it is that you can tune into a signal on a particular frequency. How can it be possible to get rid of all the other signals that are added together? I don't know how much of this makes any sense, but I have tried to specify the problem mathematically. Suppose R_1(t)...
