Introduction Th

8、is introduction is not part of IEEE Std 181-2011, IEEE Standard for Transitions, Pulses, and Related Waveforms. This standard was developed by the Subcommittee on Pulse Techniques (SCOPT). It supersedes IEEE Std 181-2003a. The SCOPT is a subcommittee of the Waveform Generation, Measurement, and Anal

9、ysis Committee (TC-10) of the IEEE Instrumentation and Measurement (I&M) Society. The SCOPT comprises an international group of electronics engineers, mathematicians, and physicists with representatives from national metrology laboratories, national science laboratories, academia, and electronic ind

10、ustries (semiconductor, computing, telecommunication, test instrumentation, and so forth). This standard facilitates accurate and precise communication concerning parameters of transition, pulse, and related waveforms, and the techniques and procedures for measuring them. Because of the broad applic

11、ability of electrical pulse technology in the electronics industries (such as computer, telecommunication, and test-instrumentation industries), the development of unambiguous definitions for pulse terms, and the presentation of methods and/or algorithms for their calculation is important for commun

12、ication between manufacturers and consumers within the electronics industry. The availability of standard terms, definitions, and methods for their computation helps improve the quality of products and helps the consumer better compare the performance of different products. Improvements to digital w

13、aveform recorders have facilitated the capture, sharing, and processing of waveforms. Frequently these waveform recorders have the ability to process the waveform internally and provide pulse parameters. This process is done automatically and without operator intervention. Consequently, a standard i

14、s needed so that the definitions and methods of computation for pulse parameters are consistent. The purpose of this revision was to update terminology, correct errors in the previous revision, and add a newly developed method for computing state levels. A Project Authorization Request (PAR) was sub

15、mitted to the IEEE Standards Board in March 2008 to develop this revision. The PAR was approved on 19 May 2008. History Between 1996 and 2003, the SCOPT prepared a revision to the now withdrawn IEEE Std 181-1977, Standard on Pulse Measurement and Analysis by Objective Techniques, and withdrawn IEEE

16、Std 194,b,-1977, Standard Pulse Terms and Definitions. These standards dealt with terms and definitions for describing and computing waveform parameters and for describing the waveform measurement process. IEEE Std 181-2003 combined the information of and superseded IEEE Std 181-1977 and IEEE Std 19

17、4-1977, both of which were withdrawn. IEEE Std 181-1977 superseded IEEE Std 181-1955. Information about IEEE Std 181-1955 and the history of the development of IEEE Std 181-1977 is located in the Foreword of the latter. The IEEE Std 194-1977 superseded IEEE Std 194-1951, IEEE Standard on Pulses: Def

18、inition of TermsPart 1. Information about IEEE Std 194-1951 is also located in the Foreword of IEEE Std 194-1977. The work that resulted in IEEE Std 181-2003 began in September 1996, when SCOPT submitted a PAR to the IEEE Standards Board to combine IEEE standards 181 and 194 into a single document a

19、nd revise the subsequently merged document. The PAR was approved on 11 December 1996 and work on the revised and combined draft began in February 1997. The PAR expiration date was December 2002. Because of delays, SCOPT and TC-10 received approval from the IEEE for a one-year extension to enable bal

20、loting and revision as required. The draft went through several major revisions that resulted in IEEE Std 181-2003. aIEEE publications are available from the Institute of Electrical and Electronics Engineers, 445 Hoes Lane, Piscataway, NJ 08854-4141, USA (http:/standards.ieee.org/). bThe IEEE standa

Other than the merger of the two withdrawn standards, IEEE Std 181-1977 and IEEE Std 194-1977, respectively, the two major changes to t

22、he content of the standard were in the parameter definitions and algorithms. Changes to the definitions included the addition of new terms and definitions, deleting unused terms and definitions, expanding the list of deprecated terms, and updating and modifying existing definitions. This standard co

23、ntains definitions for approximately 100 terms commonly used to describe the waveform measurement and analysis process and waveform parameters. Many of the terms in the 1977 versions of these standards have been deleted entirely or deprecated. Deprecated terms were kept in the standard to provide co

24、ntinuity between this and the withdrawn standards. Terms are deprecated whenever they cannot be defined unambiguously or precisely. Terms that were deleted had to do with signal shaping terminology and pulsed radio frequency signals, which were not within the scope of the standard, as determined by

25、SCOPT. Development of a set of agreed-upon terms and definitions presented the greatest difficulty because of the pervasive misuse, misrepresentation, and misunderstanding of terms. Legacy issues for instrumentation manufacturers and terms of common use also had to be addressed. These revisions also

26、 resulted in the development of algorithms for computing the values of certain waveform parameters in all cases where these algorithms could be useful or instructive to the user of the standard. The intention of the SCOPT in adding these algorithms, which are recommended for use, was to provide indu

27、stry with a common and communicable reference for these parameters and their computation. Heretofore, this was not available and there existed much debate and misunderstanding between various groups measuring the same parameters. Similarly, this is the reason the SCOPT decided to add several example

28、s of basic waveforms, with formulae. The SCOPT focused these algorithms on the analysis of two-state, single-transition waveforms. The analysis of compound waveforms (waveforms with two or more states and/or two or more transitions) is accomplished by first decomposing the compound waveform into its

29、 constituent two-state, single-transition waveforms. A method for performing this decomposition is provided. Algorithms for the analysis of fluctuation and random jitter of waveforms were also introduced into the standard. These algorithms describe the computation of the mean and standard deviation

30、of jitter and fluctuation. The standard also contains methods to estimate the accuracy of the standard deviation and to correct its value. The SCOPT added Annex A into this standard, which contains numerous figures depicting different types of waveforms. These waveform examples, with the associated

31、expressions used to generate them, help the reader understand the use of certain defined terms and provide a common ground for communicating waveform types and how they can be computed.
