Explo iting Both Time and Frequency Structure in a System
نویسنده
چکیده
In the past, it has often been assumed that when a high frequency resolution filter bank was used in a coding system, no easy access to the signal's temporal fine structure was possible. This paper presents the general framework for accessing and manipulating the temporal structure of signals by using the dual of the standard "LPC" paradigm, i.e. predicting in frequency instead of time. Examples for the application of this principle are given including the Temporal Noise Shaping (TNS) technique of the ISO/MPEG-2 Advanced Audio Coding system.

Earthquake Analysis of Base Isolated Structures Including Soil-Structure Interaction
A frequency domain dynamic analysis is needed to obtain the response of structures constructed on a system of base isolators on flexible soil when subjected to earthquake ground motion. In such systems, the lateral stiffness of the base isolators is so small, compared to the structural stiffness, that in an earthquake attack the fundamental vibration mode dominates the response. With this in mi...

Abstract General faults in regular electrical railways system could be detect by implementing the specific protection functions such as ground fault or sensitive earth fault. Otherwise, in ungrounded electrical railway systems which using both feeding and return contact rail at the same time, fault detection cannot done with above-mentioned function. Due to recent growth in electrical railway ...
متن کاملVibration analysis of a rectangular composite plate in contact with fluid
In this paper, modal analysis of the fluid-structure interaction has been investigated. Using classical laminated plate theory, a closed form solution for natural frequencies of FSI is extracted. For fluid, homogenous, inviscid and irrotational fluid flow is assumed. Then, a combined governing equation for the plate-fluid system is derived. In order to validate the equations and results, they a...
