Bench Talk

My telecoms class had an end of the year project. You know it is interesting how you do not really think about all you have learned and how fascinating and wonderful it is until the end of the semester. This telecoms project is a great example of making students think about what we learned. It involved suppressing photos and video. We had talked about bandwidth suppression all semester. It made sense. A smaller channel transmitting the same amount of information is always desirable. It was interesting to learn that since our ears, unlike our eyes, are insensitive to phase distortion it is possible to design cheaper filters that allow phase distortion to slip through.
