Abstract
In a circuit for connection of at least two signal sources with at least one signal output, the signal sources are connected with a control unit. The control unit activates or deactivates the signal sources by transmission of control signals. Each signal source is connected with a blocking unit. Each blocking unit is connected with the control unit. The blocking unit can block or enable a connection between the signal source and the signal output, with the connection being automatically enabled when the signal source is activated.
