If you were to ask me how my phone connects to wifi, I would not be able to give you any kind of technical or scientific explanation of it. In fact, I would venture to guess that this is how it is for most people. While we use these things on a daily basis, most of us have absolutely no idea how they happen to work. All I really know is that my router sends out a signal, my phone senses it, and then the two are connected wirelessly to one another. Well, prior to reading an excellent article at http://www.microchip.com, that was about all that I knew. What I did not know, which this article explains, is that most of the sensors in our tech devices actually use an analog process in order to sense what they are designed to sense, and then they use an analog to digital converter in order to show us the info on our digital interfaces.
It really is an interesting concept. For most of us, analog technology seems to be something from the Paleolithic era that is completely of the past and will never be used again. This, however, is definitely not the case, as even the most advanced digital technologies utilize some form of analog signal that is then converted to digital. It really is quite fascinating, and if you are interested in how our modern technologies work, I would definitely urge you to read the article and learn a little bit more. It really is quite enlightening.
I would guess that analog tech will always be useful for something, and that is why I found this article to be so interesting. It really is amazing the way that old and new technologies come together to make magic.
