Signal-Processing Techniques to Reduce the Sinusoidal Steady-State Error in the FDTD Method
Techniques to improve the accuracy of the finite-difference time-domain (FDTD) solutions employing sinusoidal excitations are developed. The FDTD computational domain is considered as a sampled system and analyzed with respect to the aliasing error using the Nyquist sampling theorem. After a careful examination of how the high-frequency components in the excitation cause sinusoidal steady-state...
متن کامل6.002 Lecture Notes: Sinusoidal Steady State and the Impedance Method
You’ve probably seen impedance in some context before, perhaps in a physics class, or in some discussions in an introductory lab class. If so, you will remember a few formulas and perhaps how to apply them, but here I’d like to not only explain how to use impedance as a concept, but also why it works. That way, you’ll know when you can apply this method, and when it is not appropriate. The firs...
متن کاملfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
15 صفحه اولLongest Path in Networks of Queues in the Steady-State
Due to the importance of longest path analysis in networks of queues, we develop an analytical method for computing the steady-state distribution function of longest path in acyclic networks of queues. We assume the network consists of a number of queuing systems and each one has either one or infinite servers. The distribution function of service time is assumed to be exponential or Erlang. Fu...
