impulse waveshape, standard
A waveform that has a defined virtual front time and a defined virtual time to half peak value.
NOTE 1 Impulse waveshapes may be given for either voltage or current.
NOTE 2 Virtual front time is the time interval between the virtual origin and the instant when the extrapolated leading edge reaches its peak; the extrapolation is made through the 10% and 90% amplitude points for current and the 30% and 90% points for voltage.
NOTE 3 Virtual time to half-peak value is the time interval between the virtual origin and the instant when the amplitude of the trailing edge reaches 50%. This is expressed as a combined front time and time to half-peak value such as 8/20 µs or 10/1000 µs.References
