WebOct 25, 2006 · With fixed point design the dynamic range of numbers is a key concern since a much narrower range of numbers can be represented in fixed format due to the fixed word size. There are several different ways to represent a numerical value within a fixed length binary word. In this paper we will deal primarily with fixed binary word … WebIdeally, floating-point FFT implementations in custom embedded applications should be used because they offer a much higher dynamic range and, as a byproduct, bypass the design hassle of analyzing fixed-point word lengths, including how to properly scale operations to minimize word growth and avoid overflow.
