| As such, the pulse impulses sent from the controller to the motor have to have a certain minimum width for the motor to be able to register those signals. However, that signal width also cannot be too large due to the signal overlap that would otherwise occur due to each individual signal interfering with the next one. This is done by ensuring the controller sends impulse signals at a rate that is lower than the period of the impulse at its maximum frequency, resulting in impulse signals that do not interfere with one another while the width of the signal is wide enough for the motor to register the impulse. | As such, the pulse impulses sent from the controller to the motor have to have a certain minimum width for the motor to be able to register those signals.

| - | These constraints on the minimum and the maximum pulse width create a permissible range of pulse widths for each motor depending on its hardware specifications and the particular speeds it is required to be operated at. | + | These constraints on the minimum and the maximum pulse width create a permissible range of pulse widths for each motor depending on its hardware specifications and the particular speeds it is required to be operated at. Such an optimal pulse width for the controller based on these particular specifications can be calculated. |
