protel 99se 使用技巧以及常見問題解決方法:里面有一些protel 99se 特別技巧,還有我們經常遇到的一些問題!如何使一條走線至兩個不同位置零件的距離相同? 您可先在Design/Rule/High Speed/matched Net Lengths的規則中來新增規則設定,最后再用Tools/EqualizeNet Lengths 來等長化即可。 Q02、在SCHLIB中造一零件其PIN的屬性,如何決定是Passive, Input, I/O, Hi- Z,Power,…..?在HELP中能找到說明嗎?市面有關 SIM?PLD?的書嗎?或貴公司有講義? 你可在零件庫自制零件時點選零件Pin腳,并在Electrical Type里,可以自行設定PIN的 屬性,您可參考臺科大的Protel sch 99se 里面有介紹關于SIM的內容。 Q03、請問各位業界前輩,如何能順利讀取pcad8.6版的線路圖,煩請告知 Protel 99SE只能讀取P-CAD 2000的ASCII檔案格式,所以你必須先將P-CAD8.6版的格式轉為P-CAD 2000的檔案格式,才能讓Protel讀取。 Q04、請問我該如何標示線徑大小的那個平方呢 你可以將格點大小設小,還有將字形大小縮小,再放置數字的平方位置即可。 Q05、請問我一次如何更改所有組件的字型 您可以點選其中一個組件字型,再用Global的方法就可以達成你的要求。

This packet is a IS-95 baseband simulation for 1 data channel of 9.6 KBps rate. The simulation is written for static channel and AWGN noise. The packet include: 1) Packet Builder (Viterbi Encoding, Interleaver, PN generation) 2) Modulator (RRC filter) 3) Demodulator (matched Filter, RAKE receiver) 4) Receiver (HD or SD) (Deinterleaver, Viterbi Decoder). You should run "Simulation.m" function that include all modules.

A new cable fault location method based on wavelet reconstruction is proposed. In this method the difference between the currents of faulty phase and sound phase under the high voltage pulse excitation is used as the measured signal and is decomposed in multi-scale by wavelet transform, then reconstructed in single scale. Comparing with traditional fault location method by travelling wave, the presented method will not be interfered by the reflected wave from the branch joint of cables or from other positions where the impedances are not matched and not be influenced by fault types, otherwise, the reflected waves can be recognized even the faulty position is near to the measuring terminal, at the same time, the influence of the wave speed uncertainty can be reduced. The correctness of the proposed method is proved by simulation results.

外國人開發的電磁時域有限差分方法工具包 Electromagnetic Finite-Difference Time-Domain (EmFDTD) is a basic two-dimensional FDTD code developed at the School of Electrical Engineering, Sharif University of Technology. This code has been written based on the standard Yee s FDTD algorithm. Applications include propagation, scattering, and diffraction of electromagnetic waves in homogeneous and non-homogeneous isotropic media for in-plane propagating waves. Negative permittivites or permeabilities as well as dispersion is not included. Zero, Periodic, and Perfectly matched Layer boundary conditions may be selectively applied to the solution domain. The program is best suited for study of propagation and diffraction of electromagnetic waves in Photonic Crystal structures. EmFDTD is written in MATLAB language and has been tested under MATLAB 5.0 and higher versions.
