During the simulation time step from to (step size = found ,number,integer} masked zero crossings, i.e., signal(s) with an even number of zero crossings. The search algorithm only detected these zero crossings because of the presence of other zero crossings in this time step. Masked zero crossings are caused by one or more zero crossing signals that have an even number of zero crossings in the current time step. Masked zero crossings may not be detected in all cases.
