| Abstract: | We consider a measurement of finite-frequency current fluctuations, using a resonance circuit as a model for the detector. We arrive at an expression for the measurable response in terms of the current-current correlators which differs from the standard (symmetrized) formula. The possibility of detection of vacuum fluctuations is discussed. Pis’ma Zh. éksp. Teor. Fiz. 65, No. 3, 280–284 (10 February 1997) Published in English in the original Russian journal.
