In this article we study a particular method of detection of chirp signalsfrom coalescing compact binary stars -- the so-called dynamical tuning, i.e.amplification of the signal via tracking of its instantaneous frequency by thetuning of the signal-recycled detector. A time-domain consideration developedfor signal-recycled interferometers, in particular GEO 600, describes thesignal and noise evolution in the non-stationary detector. Its non-stationarityis caused by motion of the signal recycling mirror, whose position defines thetuning of the detector. We prove that the shot noise from the dark port andoptical losses remains white. The analysis of the transient effects shows thatduring the perfect tracking of the chirp frequency only transients fromamplitude changes arise. The signal-to-noise-ratio gain, calculated in thispaper, is ~ 16 for a shot-noise limited detector and ~ 4 for a detector withthermal noise.
