This work focusses on the characterization of the stability crossing curves in the parameter space defined by the pair (gain, delay) for a class of SISO systems subject to delayed output feedback. The frequency-domain approach considered in this paper makes use of some geometric arguments, which simplifies the understanding of the stabilizing delay mechanism. Various examples complete the presentation.
