Abstract This paper is intended to provide an introduction to IEEE-STD-1241 [IEEE 1241, IEEE draft standard for terminology and test methods for analog-to-digital converters], a draft standard for analog-to-digital converters (ADCs). This standard has been generated by the IEEE TC-10 working group and is intended to establish common terms, definitions, and test methods for ADCs. The TC-10 ADC Subcommittee is coordinating with the IEC to insure that these two organizations can support one international standard for ADCs. In this paper, the basic contents of the standard are described followed by examples of applications of the test methods from the standard. Testing procedures and results are included for specific ADCs used in video and in telecommunications. These practical examples are intended to emphasize the value of having an accepted standard for terms and test methods associated with testing and specifying ADCs.
