WebFixed-Point Behavior Care must be taken when using the fixed-point versions of the FIR filter functions. In particular, the overflow and saturation behavior of the accumulator … WebUsing fixed point arithmetic usually implies you are computationally bound by a chip without an efficient floating point arithmetic unit and the numerical properties of fixed point arithmetic tend to limit the accuracy of high order filters. So high order filters are not aided by fixed point arithmetic.
