摘要： A harmonic-rejection modulation device is provided, which includes a phase splitter, a low pass filter, and a modulator. Based on a square wave, the phase splitter generates a plurality of unfiltered local oscillating signals having phase angles of 0°, 30°, 90°, 120°, 180°, 210°, 270° and 300°, respectively. The low pass filter filters the high frequency components of the unfiltered local oscillating signals to generate a plurality of local oscillating signals having phase angles of 0°, 30°, 90°, 120°, 180°, 210°, 270° and 300°, respectively. The modulator modulates a baseband signal with the local oscillating signals, wherein the third harmonics of the local oscillating signals are eliminated by the modulation process of the modulator. The invention also provides a method of modulating a baseband signal.

摘要： A wireless communication device. The wireless communication device comprises first and second programmable frequency dividers, a mixer, a modulator, a phase detector, and a variable controlled oscillator. The first programmable frequency divider divides the frequency of a reference signal by a factor N to generate a modulating signal. The second programmable frequency divider divides the reference signal by a factor M and outputs a frequency-divided signal. The facts N and M are positive integers. The mixer down-converting a transmission signal according the divided signal and outputs a translation-loop signal. The modulator modulates the modulating signal with baseband signals, and outputs a comparison signal. The phase detector detects a phase difference between the comparison signal and the translation-loop signal. The variable controlled oscillator modifies the transmission signals according to an output of the phase detector.

摘要： A retractable cable mouse includes a casing, a cable reel member, a connector, a sliding member, and an elastic element. The connector is coupled with the cable reel member and contacted with the sliding member. The elastic element is contacted with the sliding member and coupled with the casing. When the sliding member is moved to a first position, the connector is stored within the casing, and the sliding member is sustained against elastic element, so that the elastic element is compressed. When the sliding member is pulled out of the casing, the compressed elastic element provides an elastic force. In response to the elastic force, the sliding member is moved to a second position. Meanwhile, a perforation of the casing is blocked by sliding member, so that the external dust or foreign material fails to be introduced into the internal portion of the casing.
