    • The present invention relates to video data transmitting apparatus using a metallic body, comprising: an observation camera part in which is transmitted through metallic body of a motor such as automobile, ship, aircraft, and etc. to amplify modulated signal by wideband RF (Radio Frequency) amplifier, the modulated signal in which is modulated as PM (Phase Modulation) by PLL (Phase Locked Loop) process for sound and video signal inputted from mike and camera, the mike and the camera is run using by motive power for electronic power of automobile itself; and a camera control part in which outputs through audio and video output after amplifying modulated signal as stabilized level, the modulated signal in which is modulated as PM by stabilized PLL process, the stabilized PLL process in which is stabilized and amplified output of transmitted sound and video signal through the metallic body of the motor for camera shooting from the observation camera. Therefore, the present invention provides simple installation and high performance of stable transmission rate because it is not connecting with wires separately but directly connecting to metallic body for receiving sound and video signal as transmitting through metallic body for transmission of sound and video signal of from mike and camera, and to provide of high definition screen for camera shooting as transmitting wideband signal to apply phase modulation process to be modulated phase by stabilized PLL process as not to be emitted necessary spurious radiation power to outside.

    • An automated method of analyzing crosstalk in a digital logic integrated circuit on a digital computer is described. The method uses available software to make an extracted, parameterized netlist from a layout of the integrated circuit. The netlist has gate and black box invocations as well as transistor invocations. Library models are used to find driving resistances and capacitances associated with the gate and black-box invocations. For at least one potential victim wire of the plurality of wires, a subset of the wires of the chip are found to be potential aggressor wires to the victim wire. The aggressor wires are combined into a common aggressor. A risetime of the common aggressor is calculated and used to calculate the magnitude of coupled noise on the victim wire induced by the aggressor wires. An alarm threshold for each potential victim wire is determined based upon the type of logic gate that receives the victim wire. The alarm thresholds for each potential victim wire are compared to the calculated height of a coupled noise on the victim wire to determine which, if any, wires of the design suffer enough crosstalk noise that they should be redesigned.
    • 描述了一种在数字计算机上分析数字逻辑集成电路中的串扰的自动化方法。 该方法使用可用的软件从集成电路的布局中提取一个提取的参数化网表。 网表具有门和黑盒调用以及晶体管调用。 库模型用于查找与门和黑盒调用相关的驱动电阻和电容。 对于多条电线中的至少一个潜在的受损线,发现芯片的线的子集是与受电线的潜在的侵蚀线。 侵略者的电线被组合成一个共同的侵略者。 计算共同侵略者的上升时间,并用于计算由侵略线引起的受害线上的耦合噪声的幅度。 基于接收到受扰线的逻辑门的类型,确定每个潜在受害线的报警阈值。 将每个潜在的受扰物线的报警阈值与受害线上的耦合噪声的计算高度进行比较,以确定设计中的哪一条线(如果有的话)遭受足够的串扰噪声,则应重新设计。
