Why is it important?
The Prism is a novel finite impulse response (FIR) filter, which is fully recursive: the computational cost per sample is low and independent of the filter window length. Potential applications may be found in a wide range of IoT (and, indeed, conventional) fields such as industrial automation, transportation, healthcare, electrical power, condition and environmental (e.g., gas sensing) monitoring, and the smart home.
