PURPOSE:To make cables unnecessary for signal transmission by transmitting and receiving radio waves modulated with a digital signal transmitted from a computer. CONSTITUTION:The digital signal transmitted from an interface of a computer 6 is inputted to a transmitting part 2, and the pulse wave of the digital signal is converted to a prescribed level there, and radio waves modulated by this digital signal are transmitted. Meanwhile, a receiving part 3 demodulates the digital signal from received radio waves and shapes the waveform of them to the pulse wave and inputs them to the interface of the computer 6. Signals are transmitted between the computer and its peripheral devices or between plural computers by the transmitting part 2 and the receiving part 3. |
