    摘要： A method for dealing with attacks of malicious BOTs in a network security system includes detecting and analyzing a domain name receiving excessive DNS queries to judge the infection of a malicious BOT, registering the corresponding domain name as normal or abnormal management target, and redirecting an abnormal DNS query for the abnormal management target to a redirection processing & response system. Thereby, the automatic detection of malicious BOT attacks and the mechanism which performs the measures and the analysis simultaneously can protect the DNS servers and prevent the security accidents by malicious BOT attacks previously.

    摘要： A frequency up and down converter, in which, when down converting a high frequency signal into an intermediate frequency signal or up converting an intermediate frequency signal into a high frequency signal by controlling switching elements using a local oscillator signal, a signal with a frequency to be converted is controlled a number of times during one cycle of the local oscillator signal, whereby the local oscillator signal with a frequency lower than an original frequency may be used. Transistors are added in parallel to switching transistors disposed in a frequency down conversion unit or a frequency up conversion unit, and local oscillator signals with predetermined phases and pulse widths are provided to the gates of the transistors such that a high frequency signal or an intermediate frequency signal is transferred to an output terminal at least two times during one cycle of a local oscillator signal.

    摘要： An analog-to-digital conversion method using an RC time constant calibrator is provided. The method includes the operations of comparing a crossing time point at which a first reference signal and a second reference signal cross each other with a target time point and calibrating an RC time constant according to a result of the comparison. A length of time until the crossing time point at which a first analog signal and a second analog signal cross each other is counted based on a calibrated RC time constant. The counted value is output.
