摘要： PURPOSE: An asynchronous wireless communication apparatus is provided to simply embody a circuit and improve a data transmission speed by directly transmitting a sine wave impulse data signal of one cycle corresponding to a rising edge and a falling edge of a data pulse signal without using a carrier. CONSTITUTION: An impulse circuit unit(130) converts a rising edge and a falling edge of an output pulse into impulse data for the wireless transmission of a data pulse transmitted by a clock generator. An impulse data signalizing and amplifying circuit unit(140) converts the impulse data into an impulse data signal to be suitable for the wireless transmission and amplifies the converted impulse data signal. An amplification and level clipping unit(170) amplifies a receiving signal outputted from a receiving antenna unit(160) at a certain level and clips a uniform level or more. An impulse data dividing and detecting unit(180) divides an output signal from the amplification and level clipping unit(170) into positive(+) and negative(-) impulse data corresponding to the rising edge and the falling edge of the data pulse and detects the divided positive(+) and negative(-) impulse data. A data pulse reproducing unit(190) composes the impulse data detected in the impulse data dividing and detecting unit(180) as a positive(+) set pulse and a negative(-) set pulse, arranges the positive(+) set pulse and the negative(-) set pulse on time so that the positive(+) set pulse and the negative(-) set pulse is a pair of set-reset pulse and a pair of reset-set pulse corresponding to the impulse data signal of one cycle, obtains a primary pulse of a pair of every pulse, and reproduces the data pulse.
