摘要
Prism signal processing is a new FIR filtering technique that can offer a fully recursive calculation and elegant filter design. Its low design and computational cost may be particularly suited to the autonomous signal processing requirements for the Internet of Things. Arbitrarily narrow bandpass filters may be designed and implemented using a chain of Prisms and a simple yet powerful procedure. Using the described method and system, an ultra-narrowband filter can be evaluated in fractions of a microsecond per sample on a desktop computer. To achieve this update rate using a conventional non-recursive FIR calculation would require supercomputer resources. FPGA embodiments of the system demonstrate computation efficiency and broad applications of the technique.
