I have especially taken an interest in the FM radio part in the online slideshow number five. One thing that I found interesting in the online slideshow is that the FM channels are 20 times wider than the AM channels. In the lecture we talked about how that was because at one point radio companies wanted to carry television signals on these FM channels. This never actually happened but that is the reason the channels are much wider than the AM channels.

 I think that it is important for people to understand how this simple technology works so that they have a foundation of knowledge for how the new technology works. One thing that I am learning in this class is that although our technology looks much different today than it did in the early 1900’s the foundation of it is still the same. We still use the technology that we discovered in the early 1900’s to make the cell phone that you see today. The foundation of it is the same and new technology will probably always have the same foundation. We just build onto it as it evolves.
