WebMay 29, 2024 · An IIR filter is recursive which means it takes the past values of the output (equivalently it could be expressed as infinite sequence of the input). Suppose you have the filter. y[n] = b*x[n]-a*y[n-1] Generally the first output is … WebMay 31, 2006 · Inside iir () , a “while true” loop continuously reads a new reference value u , updates the states x1 , x2 , and x3 , and then calculates and writes the output. The IIR uses four (fixed-point or floating-point) adders and three (fixed-point or floating-point) multipliers. Observe how the values of all states are simultaneously updated.
