Summary:Floating-point arithmetic offers several benefits in digital signal processing. Floating-point A/D- and D/A-converters are needed in the realization of true floating-point signal processing systems. Novel, simple floating-point A/D- and D/A-conversion methods, based on the close resemblance of floating-point and logarithmic number representations, are introduced in this paper. These methods are easy to tailor to different specifications, and they offer a simple trade-off between dynamic range and accuracy.< >
