Description

In many advanced control problems such as state estimators Kalman filters and some high Q filters the dynamic range/accuracy of the coefficient can sometimes be beyond the range of a Q15 number while the data value can be typically represented as a Q15 number.This document discusses how you can extend the fixed-point math dynamic range beyond the range of a Q15 number with a minimum of instr
