For questions about processing signals of any physical quantity, with the help of Machine Learning or Artificially Intelligent algorithms.

Signal processing concerns the analysis, synthesis, and modification of signals, which are broadly defined as functions conveying, "information about the behavior or attributes of some phenomenon", such as sound, images, and biological measurements. For example, signal processing techniques are used to improve signal transmission fidelity, storage efficiency, and subjective quality, and to emphasize or detect components of interest in a measured signal.
