Abstract
A circuit arrangement for optionally amplifying one of two signals (from 2 or 6 respectively) in which at least one of the signals is supplied via a switchable signal path interruption which is inhibited when no signal is applied thereacross, and to which in this state a signal voltage is applied to both ends, which is associated with the signal to be amplified and which has already been amplified, respectively. When such a structure of a circuit arrangement is used, no damage to the circuit structure can occur, even when a signal path is interrupted in normal operation.
