                             0 r/min command to the motor. This is confirmed by my observations that no motor rotations
                             were happening and that there were zero power pulses sent from the ESC to the motor, as
                             shown in Figure 6.13.
                                The next test generates the waveform for a 100% throttle position. Figure 6.14 shows the
                             waveform out of the AR8000 with the throttle set at 100%. This waveform now shows a
                             1.88-ms pulse-width again with a 22-ms period, which is the 100% throttle setting. The motor
