This is a plot of normalized pressure amplitude for one period. The amplitude starts at 0.0, increases linearly to 1.0 at period = 0.2, remains at 1.0 until period = 0.3, decreases linearly to -1.0 at period = 0.7, remains at -1.0 until period = 0.8, then increases linearly to 1.0 at the end of the period.
