  • Process and circiuit arrangement for the transmission of digital control data
    Patent number: 5820081
    Abstract: The invention concerns a process and a circuit arrangment to transmit digital control data, preferably between a central station and individual locomotives of a model railway. In order to make possible an association between transmitters and receivers with strongly dispersed frequencies, the receiver frequency is to be adapted to the transmitter frequency. The step width of the adaptation and therefore of the synchronization is to be determined differently.
