A discussion of the IEEE standard on transition and pulse waveforms, Std-181-2003

The IEEE Std-181-2003, which is a new standard on pulse techniques and definitions, has been recently published. This standard was written to replace the withdrawn IEEE standards, Std-181-1977 and Std-194-1977. The Std-181-2003 combines information from both of the withdrawn standards. The new standard has incorporated new definitions not contained in the withdrawn standards and deleted and clarified definitions contained in the withdrawn standards. The new standard also provides examples of different waveform types and incorporates algorithms for computing waveform parameters, both of which were not contained in the withdrawn standard. This paper introduces the Std-181-2003 by describing its contents and changes relative to the withdrawn standards.
