Otto Brune coined the term positive-real for that class of analytic functions that are realisable as an electrical network using passive components.
9.
Otto Brune showed that if the case is limited to scalar PR functions then there was no other theoretical reason that required ideal transformers in the realisation, but was unable to show that transformers can always be avoided.
