 \section{Prestudy}
 Since not much was known about the project at this time, it was difficult to find relevant papers on the topic of the standards.  Most of the literature was found during the project as new problems was found along the way.

 \subsection{Test pulse 3a and 3b}
 Test pulse 3a and 3b simulates transients ``which occur as a result of the switching process'' as stated in the standard \cite{iso_7637_2}. The formulation is not very clear, but is interperted and explained by Frazier and Alles \cite{comparison_iso_7637_real_world} to be the result of a mechanical switch breaking an inductive load. These transients are very short, compared to the other pulses, and the repetition time is very short. The pulses are sent in bursts, grouping a number of pulses together and separating groups by a fixed time.

 \subsection{Test setup}
 During a test, the nominal voltage is first applied between the plus and minus terminal of the DUT's power supply input. Then a series of test pulses are applied between the same terminals. The pulses are repeated at specified intervals, $t_1$, as depicted in \autoref{fig:doubleexprep}.
