KEYWORDS: Timing, clock, delay, waveform generator, synchronization

One important use 6f the K(clock) and K(delay) is in the design of waveform generators. These systems take input parameters and create an output waveform, Output(t), which varies with time. The simplest digital-type waveform that can be generated is the symmetrical square wave. It is represented graphically and functionally in Figure SW-1. With this function the sampling time between changes of the function is equal to half the period of the function, T/2. The function changes in discrete steps, hence, the Output(t) is 0 or 1, rather than begin continuous.

Design a waveform generator which will behave according to the square wave function.
