Once the pulses and their associated power have been determined, the time when they occured must be found. The peak of the windowed triangle waveform occurs at the right side, or end of the pulse. Pulses begin 1.5 ms before the triangle peak, and the center of the pulses occurs 0.75 ms before the triangle wave peak. These three values, the center and both edges of the pulse, are stored to define the timing of the peak. The simulation model records these three values as well. Timing is compared by taking the difference between the three points of each real pulse and the three points of each simulated pulse.
