Abstract: A microcontroller receives, from a device, an input signal having a value. The first microcontroller generates an adjusted value by adjusting the value to an adjusted value within a range of tolerance of a state determination system, and determines a first range of the adjusted value, the first range being within one of an asserted range, an unasserted range, or a fault range. The first microcontroller compares the first range to a second range, the second range derived based on one or more of a different input signal or a different microcontroller, and determines a result of the comparison, the result being an asserted state where the first range and the second range both are within an asserted range, the result being an unasserted state where both ranges are within an unasserted range, and the result otherwise being a fault state, and outputs the result to an output controller.
