Abstract
Noise waves are a powerful means for characterizing noise in microwave circuits. A simple derivation is given for the relation between a passive circuit´s noise-wave correlation matrix and its scattering matrix. It is shown that this relation, referred to as Bosma´s theorem, can be readily derived from the fundamental principle that a passive multiport in thermodynamic equilibrium with reflectionless terminations produces uncorrelated output waves.<>
