Modern communications systems rely on increased signal complexity to pack more data into each symbol transmitted. These complex signals can result in data dependent, high peak-to-average power ratios ...

Astronomers have long struggled to clock the speed and power of Cygnus X-1, a ...

This very subject came up recently in the Audioholics forum and I would like to expand on this subject further, but before I do I think it's important to go into the history of how this specification ...
