  • Abstract:
    A new procedure for determining the size and the values of a look-up table for reconstructing the measurand values in a measurement system employing a non-linear sensor is presented. This procedure uses the A/D converter quantization error to calculate the table entries. The proposed methodology is illustrated applying it to a thermistor based thermometer.
