trapezoid waveform is represented by 100 time units. The sum of ramp up and ramp down cannot
exceed 100. If the sum of ramp up and ramp down is less than 100, the remaining time has no ramp,
shown as t
a
below.
Using the trapezoid waveform, you can generate a square wave (ramp up = ramp down = 0), a
triangular wave (ramp up = ramp down = 50), a saw-up wave (ramp up = 100, ramp down = 0) and
a saw-down wave (ramp up = 0, ramp down = 100) in addition to trapezoidal waveforms.
