An apparatus for correcting an input signal is configured for receiving the input signal, the received input signal comprising a series of input values. The apparatus is configured for matching a series of template values to the series of input values by warping the series of template values and the series of input values relatively to each other so as to assign one or more template values to one or more input values, wherein the series of template values represents an approximation of a noise signal that is expected to be comprised in the input signal. The apparatus is configured for obtaining a series of corrected input values based on a mismatch between the input values and their respective assigned template values. The apparatus is configured for providing a corrected signal based on the series of corrected input values.

Apparatus and method for correcting an input signal

A MEMS device includes a MEMS sound transducer, and control circuitry. The control circuitry includes a supply signal provider for providing a high-level supply signal and read-out circuitry for receiving an output signal from the MEMS sound transducer, and a switching arrangement for selectively connecting the MEMS sound transducer to the supply signal provider, and for selectively connecting the MEMS sound transducer to the read-out circuitry based on a control signal. The control circuitry provides the control signal having an ultrasonic actuation pattern to the switching arrangement during a first condition TX of the control signal, wherein the ultrasonic actuation pattern of the control signal triggers the switching arrangement for alternately coupling the high-level supply signal to the MEMS sound transducer.

A gas sensing device includes a photoacoustic spectrometry device, including a radiator for emitting light, a gas detection chamber for exposing a mixture of gases to the light, a microphone for detecting sound in the detection chamber, which is caused by exposing the mixture of gases to the light, and wherein the photoacoustic spectrometry device generates signal samples corresponding to a concentration of the gas in the mixture of gases based on the sound detected by the microphone, and a computing device for receiving the signal samples. The computing device includes a feature extraction block including a trained model algorithm block.
