The ring modulator as a polarized rectifier

The performance of the ring modulator as a phase-sensitive rectifier is described qualitatively. Under the assumption of idealized conditions, and with the use of the analytical approach originally developed for the ring modulator, the polarized rectifier is described quantitatively, both for steady state and transient state. The analytical findings are checked experimentally. A differential polarized rectifier functioning as a true null detector is also discussed.
