摘要： An apparatus and a method for adaptively calculating a start position of a series of symbols are provided. The method is applied to a frame synchronization circuit that implements the apparatus for calculating the symbolic start position of a packet-switching communication system. Even under the situations such as higher frequency offset, the frequency offset value approaching zero or unstable frequency offset, the frame synchronization circuit using the claimed method still can estimate the symbolic start position. The preferred method includes a first step of retrieving the signals in a unit of packets, and calculating their delay correlation value. Next, a control circuit is incorporated to retrieve multiple groups of symbols, and to set the parameters of the systems as a basis for identifying the system's property. After that, it's to estimate the symbolic start position.

摘要： A KVM switch and an operation method thereof can share at least one USB device to a plurality of computers, and the computers can directly communicate with the USB device through a switch module. The KVM switch further comprises a microprocessor and a USB controller. When switching in the KVM switch, by using the set information command in USB specification, the microprocessor can control the USB controller to interfere in setting the USB device to become receiving a signal sent by the computer which recognition data is representative. Then, the computers need not execute the enumeration process to recognize the USB device in every switching time. Hence, the KVM switch can improve the compatibility problem and increase switching efficiency.

摘要： A frequency synthesizer applied to a frequency hopping system includes a voltage controlled oscillator (VCO), a phase lock loop (PLL) system, a second frequency divider, a first SSB mixer, a second SSB mixer, and a multiplexer. The VCO generates an oscillating frequency. The PLL system includes a first frequency divider and divides the oscillating frequency by 10 to generate a first dividing signal. The second frequency divider divides the oscillating frequency by 2 to generate a second dividing signal and further divides the second dividing signal by 2 to generate a third dividing signal. The first SSB mixer mixes frequencies of the second and third dividing signals to generate a first mixing signal. The second SSB mixer mixes frequencies of the first mixing signal and the first dividing signal to generate a second mixing signal. The Multiplexer determines to output the first mixing signal or the second mixing signal.
