Abstract
A sensor () for measuring a variable generates a sensor signal (S), oscillates at a drive frequency (f), and includes: a rate demodulator (), which demodulates the sensor signal (S) by multiplying it by a first demodulation signal, in order to generate a rate signal (R), which contains information about the measured variable to be measured; a quadrature demodulator (), which demodulates the sensor signal (S) by multiplying it by a second demodulation signal shifted by 90° with respect to the first demodulation signal, to generate a quadrature signal (Q); and an analysis circuit (), which determines whether the quadrature signal (Q) or a signal (Q) derived therefrom is subject to a periodic oscillation and, if a periodic oscillation is present, outputs a status signal (X) having a value which indicates that the instantaneous rate signal (R) is influenced by an external interference acting on the sensor ().
