Abstract

Signal processing engineers recognise two main classes of filter: Finite Impulse Response (FIR) and Infinite Impulse Response (IIR), each with distinct properties. The Prism is a new filter type which combines the best of both: the numerical stability and linear phase of FIR, together with the low-cost calculation of IIR. Here, we show how to build ultra-narrowband FIR filters, containing over one billion samples (taps), using a sequence of Prisms. While designing and operating equivalent conventional FIR filters would require supercomputer resources, these Prism filters are designed instantly and implemented on a single FPGA.
