Abstract

Since naturally occurring physical phenomena such as temperature, pressure, displacement, and so on, are analog, and since most practical methods of data collection, manipulation, and analysis are digital, a conversion from the analog quantities to digital quantities must take place. This conversion is called digitization and has virtually unlimited application. The device that converts the analog signal into a digital representation is called an analog-to-digital (A/D) converter. In this chapter we shall discuss the fundamental aspects of the conversion process that are common to most applications. Although there are numerous methods and techniques for converting an analog signal to a digital number only three will be discussed. The details of the implementation of the various methods can be found in many of the references given at the end of the chapter.
