Figure A-1. UltraCAD’s Square Wave Simulator.
A square wave does not exist naturally in nature. We can think of a square wave as actually being formed by, or made up of, a series of natural cosine waves following the relationship:
where ω is the fundamental frequency of the wave and t is time. The ...
