ABSTRACT:
An arrangement for wireless transmission of signals using a serial two-conductor data bus, the arrangement including 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 effects modulating the oscillator generated signal in dependence on the clock conductor signal and the data conductor signal respectively. 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 signals and the other channel (5,10) is intended for the clock signals. 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.
