A method for stabilising a series of measurements of a physical variable comprises the steps of : capturing at least a first, second, and third measurement of said physical variable and storing each measurement in a digital memory. If a difference between the first measurement and the second measurement is below a predetermined threshold, the second measurement is replaced in the memory by a corrected second measurement where the difference with respect to said first measurement has been reduced using a first filtering strength. If a difference between the filtered value of the corrected second measurement and said third measurement is also below the threshold, said third measurement is replaced by a corrected third measurement where a difference with respect to said corrected second measurement has been reduced using a second filtering strength that is lower than the first filtering strength. This method has the advantage of filtering noise whilst still allowing slow but relevant variations in the series of measurements. |
