An application of physical units (dimensional) analysis to the consideration of nonlinearity in electrical switched circuits

The argument of physical dimension/units is applied to electrical switched circuits, making the topic of the nonlinearity of such circuits simpler. This approach is seen against the background of a more general outlook (IEEE CAS MAG, III, 2009, pp. 56-62) on singular (switched and sampling) systems. The appendix suggests some points for the axiomatization of system theory considered as an independent science.
