With the further development in astronomy and deep space exploration, the incremental improvements to be expected in the very long baseline interferometry (VLBI) is real-time, high sensitivity, high reliability and wider frequency coverage. The VLBI

An extension to the analytical design of digital equiripple comb FIR filters is presented here. The filters are optimal in Chebyshev sense. The design runs from the filter specification through the degree formula to the impulse response coefficients,

As the minimum feature size of VLSI technologies scales down, more of the signal processing tasks are performed in the digital domain. This results in increased speed, resolution, and dynamic range requirements for the analog-to-digital converter (AD

In this article, we introduce a mixed method for the application of nonlinear electric networks in order to establish a system description, which can be easily formulated and simulated with the aid of the so-called differential algebraic equations (D

Mathematical models for two kinds of capacitor voltage transformer (CVT) with various states, i.e., zero load state, normal load state, short-circuit state of the primary side, and short-circuit state of the secondary side are presented. Digital simu

A digital simulation model of the fault states of high-voltage three-phase current short distance ring systems is introduced with the aid of the software MATLAB SIMULINK. The stability of the integration in the digital simulation model is discussed.

We establish a general theorem of quasi-energy conservation for the electromagnetic scattering problem in the time-dependent and time-harmonic cases. This theorem expresses two bilinear relationships between two distinct electromagnetic states, which

This paper addresses the problem of time-harmonic electromagnetic three-dimensional scattering in dissipative or dielectric media. A field approach to the well-known boundary integral formulation is derived from a general identity between two distinc
