摘要： A method of monitoring an analog signal output from a sensor comprising comparing the amplitude of the analog signal to a first high and low threshold, setting a primary monitoring signal to a first value when the amplitude of the analog signal exceeds the first high threshold, setting the primary monitoring signal to a second value when the amplitude of the analog signal decreases below the first low threshold, comparing the amplitude of the analog signal to a second high and low threshold, setting a secondary monitoring signal to a first value when the amplitude of the analog signal exceeds the second high threshold, setting the secondary monitoring signal to a second value when the amplitude of the analog signal decreases below the second low threshold, comparing the primary and secondary monitoring signals and determining from the comparison whether an error exists with the monitoring of the analog signal.
