A microphone or a microphone sensor system operates with a sensor interface that receives a supply voltage at a supply terminal. The sensor interface detects a command at the supply terminal based on a change in the supply voltage and communicates the command or data related to the command to a component of the sensor system. The supply terminal is a bidirectional terminal that further communicates data related to the sensor system via the supply terminal.

Microphone configuration and calibration via supply interface

A method and a device for interpolating or decimating a signal is provided, the signal being processed by a plurality of signal processing means connected in series, which at least comprise means for increasing or reducing a clock rate of the signal and filtering means. To achieve adaptation to different operating modes or transmission standards, individual portions of the signal processing means connected in series can be bridged by bypasses. In addition, filtering parameters of the filtering means can be varied and factors, by which a clock rate of the signal is increased or reduced, can be changed.
