same time width until the next edge occurs.
modulation waveform is reset in synchronization with the rising edge of the HU signal at every electrical
angle of 360°. Thus, when the Hall signal rising edge is off-position or during acceleration or deceleration,
the modulation waveform is non-consecutive at every reset.
In the above diagram, the modulation waveform (1)
If the next edge does not occur after the 32 data items end, the next 32 data items move forward by the
The phases are matched between every rising edge of the HU signal and the modulation waveform. The
The modulation waveform is generated using Hall signals. The modulation waveform is then compared
