ABSTRACT
Modern computers handle information represented as discrete binary voltages. However, to influence and interact with the external world, the computer must produce results that are analog, or continuously varying. This interfacing of the computer to the real world is achieved through devices that convert voltages to and from the analog domain. These special devices are called Analog to Digital Converters (ADCs) and Digital to Analog Converters (DACs). ADCs and DACs map the infinite levels of analog voltages to a discrete, finite set of digital levels.
