SineWave

** SineWave** is a periodic signal generator block that generates a sine wave. There are 5 controlling parameters:

SAMPLE_RATE is in units of samples per second, DURATION is measured in seconds, FREQ in cycles per second and PHASE in radians. The sine wave has maximum and minimum values of +AMP and -AMP.
