The Signal connects everything to everything else, in both communication, and in the metaphorical sense as the link between and among people.
"Lewis (emer., Naval Postgraduate School) offers a personal view of the history of signal processing. The historical aspect is accessible, but the mathematics is not for beginners.
Still, this work provides a brief overview of important advanced concepts in approximately historical order and might serve well in advanced courses as a basis for understanding just how much there is to grasp about signal processing."
