    摘要: Provided is an apparatus and a method of measuring a distance between devices using a low clock frequency signal. The apparatus includes clock frequency generators, counters, a controller and a calculator for determining the distance based on clock signal overlap. Radio waves are transmitted and a number of clocks of a clock signal having a clock frequency b are counted, and if the transmitted radio waves are received again, a number of clocks of a clock signal having a clock frequency a are counted. If the clock signals having the clock frequencies a and b overlap with each other, counting of the numbers of the clocks of the clock signals having the frequencies b and a stops, and the distance is measured using the count values of the clock signals having the clock frequencies a and b. As a result, number of clocks of clock signals having low clock frequencies with a uniform difference can be counted to precisely measure a distance.

    摘要: A parallel coupled line filter is miniaturized by using lumped capacitors and grounding the capacitors. The parallel coupled line filter includes a parallel coupled line, a first capacitor connected to one of two input ports of the parallel coupled line, and a second capacitor connected to one of two output ports of the parallel coupled line. The parallel coupled filter can be miniaturized to a desirable size, on the basis of relatively simple theoretical knowledge. The parallel coupled line filter exhibits excellent frequency selectivity and improved harmonic characteristics.

    摘要: A wireless communication terminal capable of changing a channel, and a channel changing method of the wireless communication terminal. The wireless communication terminal generates a plurality of channels by dividing at least part of a frequency band for ultra-wideband communications into a plurality of frequency sub-bands, receives a radio signal in at least one of the plurality of the channels, and changes a channel for receiving the radio signal. Accordingly, high quality communications are feasible between the transmitter terminal and the receiver terminal in an optimized channel environment, and signal interference between the receiver terminals connected to different transmitter terminals can be prevented. Additionally, it is possible to carry out the channel change rapidly and efficiently and to reduce the power consumption required to transmit and receive radio signals comprising a chaotic carrier signal.
