  • Method and apparatus for determining weighted average of process variable
    Patent number: 4926364
    Abstract: A method and apparatus for determining a weighted average of three input values under the control of a processor includes a step of determining which of the three input values is the median value, with the remaining input values being first and second values. Then, first and second weighting factors are calculated based on a predetermined median weighting factor and the three input values. Finally, a weighted average is calculated based on the first and second weighting factors, the predetermined median weighting factor, the first and second input values and the median input value. The three input values may be sensed values provided by a temperature sensor in a nuclear power plant.
