Abstract: 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.

Abstract: 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.

Abstract: This application provides a circuit arrangement for a circuit output structure that generates ternary signals. The output structure includes a switching means for connecting a signal output with a first potential for producing a first signal level. A further switching means connects the signal output with a second potential for producing a second signal level. The signal output also is connected through a resistance means to a third potential that provides a third signal level. The switching means and the further switching means may decouple the signal output from the first potential and the second potential when a control voltage for controlling the switching means and the further switching means is removed or floats. When the first potential and the second potential are decoupled, the signal output may attain the level of the third potential.
