    摘要： An open loop resonator filter employed aperture on the ground plane is disclosed. The open loop resonator filter using apertures on the ground plane formed on the dielectric substrate, the open loop resonator filter including: one or more open loop resonators formed on a upper side of the dielectric substrate and implemented by microstrip lines; and one or more apertures formed on a predetermined area of the ground plane. The present invention can control the coupling coefficient of the open loop resonator without degrading the group delay characteristics by forming the aperture on the ground plane. Therefore, by forming the aperture on the ground plane, it is possible to design a filter having a wide bandwidth characteristic.

    摘要： A timing loop controller for multilevel modulation scheme is disclosed. The timing loop controller includes a first to fourth computing unit for computing a timing error between an input timing of digital signals and a sampling timing; a first to fourth quantization unit for controlling a direction and an error value of the timing error; a first and second sign detection unit for detecting sign change according to results; a zero crossing detection unit for detecting zero crossing at I axis and Q axis; and a timing error control unit for controlling the timing error value in case there is no sign change. The present invention can increase a zitter performance of timing error according to the signal-to-noise ratio by detecting the timing error, outputting the timing error and controlling the timing error output value only in case there is sign change by additionally equipping the sign variation detector.

    摘要： Disclosed herein is an apparatus for controlling the capacity of an air conditioner and a control method using the same. The capacity control apparatus is configured in such a fashion that a 3-way or 4-way direction-switching member and a low-pressure equalizing solenoid valve are provided at a refrigerant path of the air conditioner having a pair of first and second compressors, so that the compression capacity of the air conditioner is adjusted into three stages of 100%, 60%, and 40% using the first and second compressors, enabling easy variable-capacity operation. This has the effect of considerably reducing energy consumption and of preventing wear of the first and second compressors via a rapid compensation of a pressure unbalance between both the compressors. As a result, under any operating condition, it is possible to prevent a liquid backflow phenomenon from occurring when starting operation of the compressors, resulting in an improvement in the reliability and operation efficiency of the compressors.
