Abstract: An analysis is made of the feasibility, in principle, of detection of a classical signal with unknown parameters against the quantum noise of an optical small-displacement transducer. This is done for an optimally synthesised compensator of excess losses, which are typical of parametric three-frequency systems under a priori known constraint conditions.
