I have no idea what this has to do with anything. I was generally confused for half of class and just wrote a bunch of notes that probably don’t make sense.

Mostly because signal to noise ratio is boring and I’m not sure if we talked about analog computers or not, but it is interesting that signal to noise ratio can be analyzed through everyday concepts.  When I think of signal vs. noise, I think electrical signal you hear vs. everything that’s not the signal. As we learned, noise is a general deterioration of signal as its traveled. But, anything you don’t like can be deemed noise. It reminds me of anytime you see a TV show and the kid is playing music, the mom always says,”Turn that noise off!” The idea that outside sound or noise disconnects the natural order.

So, how you determine what is signal and what is noise? When we ask questions like this class, the first idea is: it depends on the person, but why is that? It can’t possibly be true, because there has to be some way to determine non electrical signal and noise.
