  • Data transmission method and arrangement
    Patent number: 6456210
    Abstract: The invention relates to a data transmission method and a data transmission arrangement implementing the method. The data to be transferred is digital and consists of bits, the value of which is determined using voltage. In the solution, an electric current corresponding with the digital value of the data to be transmitted is formed in a current converter (3004, 3024) which is transferred on the bus (310, 312). The original digital data is restored from the electric current after data transmission using a reverse current converter (3006, 3022).
