  We consider the virtual effects of a general type of Anomalous (triple) Gauge
Couplings on various experimental observables in the process of
electron-positron annihilation into a final fermion-antifermion state. We show
that the use of a recently proposed "$Z$-peak subtracted" theoretical
description of the process allows to reduce substantially the number of
relevant parameters of the model, so that a calculation of observability limits
can be performed in a rather simple way. As an illustration of our approach, we
discuss the cases of future measurements at LEP2 and at a new 500 GeV linear
collider.
