Why do sine waves define pure frequency?
Did anyone mention that triangle, square or any other form of waves are made up of higher frequency sine waves? In sound tech school i learned that a square wave is not really square since the change from positive to negative values in a true square wave would have to happen in absolute 0 time.

Read what people in the thread have said about orthogonal functions, for the right answer to the OP.
