  • Changeover device for selecting one modulator out of two and connecting it into a transmitter
    Patent number: 4541121
    Abstract: The changeover device is intended to produce either independent operation of a transmitter with its own modulator or coupled operation with another transmitter, in which case the two transmitters employ the same modulator, this modulator being associated with either of the two transmitters. The device comprises logical means for receiving any fault signals from the modulators as soon as they are produced and the control signals for indicating the modulator which it is desired to connect and for ensuring that, in the event of a fault occurrence in one out of two modulators, the other modulator is always selected irrespective of the control signals.
