A standard electret microphone can detect sub-audio "sounds" when some simple equalization circuitry is added.

A DIY The Wrench maker has built a smart desk dustbin with an automatic iris-style lid, adding both functionality and a ...

In this paper, an analog-based phase calculation readout circuit with a 3 μs row time for an indirect time-of-flight (i-ToF) 3D image sensor is proposed. The circuit achieves the calculation of ...
