The IEEE Std 181-2011, “Standard on Transitions,Pulses, and Related Waveforms”, defines the parameters that describe the basic characteristics of transitions, pulses, and related signals and defines the computational procedures for estimating the value of these parameters. The Std. 181 has been developed and is currently maintained by the Working Group 181.
