SquareWave

** SquareWave** is a signal generator block that generates a regular square wave function. There are 5 controlling parameters:

SAMPLE_RATE is in units of samples per second, DURATION is measured in seconds, and FREQ in cycles per second. The square wave has maximum and minimum values of +AMP and -AMP. The initial PHASE is specified in radians where the one complete cycle of the wave has 2 Pi radians (see diagram below).
