IEEE 181-2025

This standard defines terms that describe the parameters pertaining to transitions, pulses, and related waveforms and defines procedures for estimating the values of these parameters.

The purpose of the standard is to unambiguously and accurately define terms pertaining to transitions, pulses, and related waveforms and the algorithm for their computation. This helps to communicate requirements between vendors and users, improves understanding and readability of instrument performance specifications, and provides a common ground for parameter and performance comparisons.

Revision Standard - Active. Approximately 100 terms and their definitions for accurately and precisely describing the waveforms of pulse signals and the process of measuring pulse signals are presented in this standard. Algorithms are provided for computing the values of defined terms that describe measurable parameters of the waveform, such as transition duration, state level, pulse amplitude, and waveform aberrations. These analysis algorithms are applicable to two-state waveforms having one or two transitions connecting these states. Compound waveform analysis is accomplished by decomposing the compound waveform into its constituent two-state single-transition waveforms.
