Chapter Twelve. Digital Data Formats and Their Effects

image

In digital signal processing, there are many ways to represent numerical data in computing hardware. These representations, known as data formats, have a profound effect on the accuracy and ease of implementation of any given signal processing algorithm. The simpler data formats enable uncomplicated hardware designs to be used at the expense of a restricted range of number representation and susceptibility to arithmetic errors. The more elaborate data formats are somewhat difficult to implement in hardware, but they allow us to manipulate very large and very small numbers while providing ...
