Agilent AN 154 S-parameter Design Application Note S参数的设计与应用 The need for new high-frequency, solid-state circuitdesign techniques has been recognized both by microwaveengineers and circuit designers. These engineersare being asked to design solid state circuitsthat will operate at higher and higher frequencies.The development of microwave transistors andAgilent Technologies’ network analysis instrumentationsystems that permit complete network characterizationin the microwave frequency rangehave greatly assisted these engineers in their work.The Agilent Microwave Division’s lab staff hasdeveloped a high frequency circuit design seminarto assist their counterparts in R&D labs throughoutthe world. This seminar has been presentedin a number of locations in the United States andEurope.From the experience gained in presenting this originalseminar, we have developed a four-part videotape, S-parameter Design Seminar. While the technologyof high frequency circuit design is everchanging, the concepts upon which this technologyhas been built are relatively invariant.The content of the S-parameter Design Seminar isas follows:

ARP test mode. According to the idea we design the arithmetic for the key part, first the system sends a message to the target machine, and then system wait for the response. Once system receives a message, it starts to analyze the message, according to the message s parameter system judges whether the message satisfies the conditions. Once the message satisfies all the conditions, the system thinks the machine is sniffing, and adds this machine into the list of sniffing machines. On this basis the detection has done well, and at the same time we insert the result into the log database for inquire and analyze later.

针对齿轮故障特征信号具有强噪声背景、非线性、非平稳性特点，提出采用形态梯度小波对齿轮振动信号进行降噪。首先使用形态梯度小波把齿轮振动信号分解到多个尺度上，然后对各层的细节系数进行软阈值方法降噪处理，对经过处理后的小波系数进行重构。对降噪后的齿轮振动信号采用S变换多分辨率时频分析，能够从具有良好的时频分辨率的S变换谱图提取齿轮故障特征。通过仿真试验和故障轴承的信号分析证明，该方法具有短时傅里叶变换和小波变换的优点，不存在Wigner-Ville分布的交叉干扰和负频率，能有效地提取隐含在噪声中的齿轮故障特征，适合齿轮故障的在线监测和诊断。
