Signal processing engineers recognize two main classes of filter: finite impulse response (FIR) and infinite (IIR), each with distinct properties. The Prism is a new filter type that combines the best both: numerical stability linear phase FIR together low-cost calculation IIR. Here, we show how to build ultranarrowband filters containing over one billion samples (taps) using sequence Prisms. W...
