Abstract
The invention relates to a method and to a measurement cell assembly for determining a pressure in a pressure cell () are given, wherein the method consists in that a measurement signal (x) is determined, which is at least proportional to a measured pressure in the pressure cell (), and in that the measurement signal (x) is filtered by means of a first filter unit () having a low-pass characteristic in order to produce an output signal (y), wherein the low-pass characteristics of the first filter unit () is defined by means of a first damping factor (α). The method is characterized in that an input difference (x_diff), which results from a difference between the output signal (y) and the measurement signal (x), is filtered by means of a second filter unit () having a low-pass characteristic to determine an output difference, wherein the low-pass characteristic of the second filter unit () is defined by means of a second damping factor (α), and in that the first damping factor (α) of the first filter unit () is determined on the basis of the output difference of the second filter unit ().
