CHAPTER 1Numerical Representation

To process a signal digitally, it must be represented in a digital format. This point may seem obvious, but it turns out that there are a number of different ways to represent numbers, and this representation can greatly affect both the result and the number of circuit resources required to perform a given operation. This chapter is focused more for people who are implementing digital signal processing (DSP) and is not really required to understand DSP fundamental concepts.

Digital electronics operate on bits, of course, which are used to form binary words. The bits can be represented as binary, decimal, octal, hexadecimal, or another form. These binary numbers can be used to represent “real” numbers. There are ...
