An arrangement for wireless transmission of signals via a serial two-conductor data bus, comprising a clock conductor and a data conductor connected to a transmitter, a receiver and a demodulator, the transmitter including an oscillator, and further including a modulator which is effective modulating the oscillator generated signal in dependence on the clock conductor signal and the data conductor signal respectively. The invention is characterised in that the modulator (3) is operative in carrying out on the oscillator generated signal two significant, separate modulation steps which do not coincide in time, thereby to form two mutually independent signal channels (4, 8; 5, 10), of which a first channel (4, 8) is intended for data and the other channel (5, 10) is intended for the clock signals. The arrangement is further characterised in that the demodulator (6) is operative in demodulating one thus modulated signal received by the receiver (2) and in recreating the aforementioned two signals, and also in that the demodulator has an output (9) for a clock conductor and an output (7) for a data conductor. |
