Abstract: The sensor (5) is configured to provide a digital output signal (S O ) and has a digital detector (13), which is configured to detect a physical quantity and generate a conditioned digital signal (S D ) indicative of the detected physical quantity; and a rate modification stage (15), configured to receive the conditioned digital signal and a group of parameters (K), the group of parameters comprising an interpolation factor (I 1 ) and a downsampling factor (D 1 , M), and to provide the digital output signal. The rate modification stage has an interpolator (36) and a decimation element (40, 60). The interpolator is configured to receive and to upsample the conditioned digital signal based on the interpolation factor and to provide an interpolated signal (S D,int ). The decimation element is configured to downsample the interpolated signal based on the downsampling factor, thereby generating the digital output signal.
