Modes in optical waveguides formed by silver-sodium ion exchange
Exact solutions of the scalar wave equation for the guided modes of planar optical waveguides formed by silver-sodium ion exchange have been obtained. It has been shown that there is good agreement between the exact solution ...
On optimum receivers for analog communication in impulsive noise
In this paper the problem of impulsive noise suppression in analog communication systems is considered. The problem of demodulation of amplitude and phase modulated signals in the presence of impulsive noise is formulated ...
Aggregation matrix for the reduced-order continued fraction expansion model of Chen and Shieh
A relationship between the states of a high-order system, and its reduced-order continued fraction expansion model of Chen and Shieh, has been derived. This relationship, in the form of an aggregation matrix, has been used ...
Digital low-pass filtering using the discrete Hilbert transform
A matrix formulation for a digital low-pass filter, alternative to that given by Sabri and Steenaart, is presented. It is shown that the new formulation offers computational advantages and has better noise performance.
Identification of stochastic time-delay systems
A method is presented to identify time lags present in systems described by linear, stochastic dynamical models usually encountered in process control. The model equation is first discretized and converted into a ...
On simplification of unstable systems using Routh approximation technique
A modified modeling procedure using the direct Routh approximation method (DRAM) for a class of unstable systems has been presented in this technical note. The proposed method yields a model which is based on an improved ...
Design of IIR filters using Pseudo-Boolean methods
Pseudo-Boolean methods are particularly suited to problems in which the variables take only two values, 0 and 1. In this paper, a method is presented for solving nonlinear pseudo-Boolean inequalities, and is applied to ...
