A reference sinusoid is encoded via a plurality of pulse trains, such that each pulse train includes a number of pulses n representing a value of the reference sinusoid out of a maximum possible pulses corresponding to an encoding quantization level. A circular register stores a representation of the encoded sinusoid. A set of multiple logical gate blocks are configured to multiply, via one or more bitwise operations, each of multiple bits of a received input signal with a pulse train corresponding to a value of the encoded sinusoid. A logic circuit coupled to the circular register and the set of multiple logical gate blocks is configured to generate, based on the encoded sinusoid and on the input signal, an output signal indicating an approximate value of the received input signal multiplied by the encoded sinusoid."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Low-power digital signal processing","description":"Systems and devices are provided to perform low-power digital filtering of sensor or other data based on bitwise operations.
