  • System and method for three input voting
    Patent number: 9092313
    Abstract: An embodiment described herein includes a method for input channel voting. The method includes steps for sorting the three input values by magnitude into a high input value, a middle input value, and a low input value. The three input values are then tested. The testing includes subtracting the middle input value form the high input value to calculate a first difference, and comparing an absolute value of the first difference to a failure threshold. A first intermediate value is determined based on the comparison of the first difference to the failure threshold. The testing also includes subtracting the middle input value from the low input value to calculate a second difference, and comparing the second difference to the failure threshold. A second intermediate value is determined based on this comparison. The first intermediate value and second intermediate value are averaged to produce an output based on the three input values.
