约翰逊的又一本SI力作，介绍如下： Raves for Dr. Johnson's previous classic, High-Speed Digital Design! "....one of the finest efforts to come along in the field of applied high-speed digital design because of its focus on providing tools for the whole design team bringing a high-speed product to life. For all the PCB designers and circuit designers out there, buy it; read it; keep it." -Dan Baumgartner, Printed Circuit Design In High-Speed Signal Propagation, Howard Johnson and Martin Graham bring together state-of-the-art techniques for building digital interconnections that can transmit faster, farther, and more efficiently than ever before. Packed with new examples and never-before-published high-speed design guidance, this book offers a complete and unified theory of signal propagation for all metallic media, from cables to pcb traces to chips. Coverage includes: Managing tradeoffs between speed and distance Physical theory of signal impairments: skin and proximity effects, dielectric loss, surface roughness, and non-TEM mode propagation Generalized frequency- and step-response models Calculation of time-domain waveforms from frequency-domain transfer functions Differential signaling: Edge-coupled and broadside-coupled differential pairs, bends, intra-pair skew, differential trace geometry impedance, crosstalk, and radiation Inter-cabinet connections: Coax, twisted-pair, fiber, equalizers, and LAN building wiring Clock distribution: Special requirements, repeaters, multi-drop clock distribution, jitter, and power filtering Simulation: Frequency domain simulation methods, Spice, and IBIS

emd的matlab代码 EMD-SA-DBN-for-Wind-speed-forecast （MATLAB CODE） Establishing a time series forecasting model for wind speed prediction based on DBN，Due to the autocorrelation of the wind speed sequence, the predicted value and the actual value lag, so EMD is used to decompose the wind speed sequence, and then the decomposed components are modeled in turn. To further mention accuracy, the simulated annealing algorithm is used to optimize the DBN。 (MATLAB代码)采用深度置信网络DBN建立风速预测的时间序列预测模型，由于数据本身的自相关性，导致得
