Limited frequency response of impulse voltage dividers contributes to the measurement errors of the peak voltage and time parameters. This paper investigates the convolution method for the determination of the errors of lightning impulse parameters due to non-ideal step responses. The step response of a damped capacitor divider with a voltage rating of 2.2 MV was measured and analytical lightni...

In most approximation techniques for implementing a variable fractional delay, the magnitude response usually varies considerably with the delay. However, it would be desirable to keep the magnitude response the same for all delay values. In this paper, we propose a novel method for optimizing the parameters of the least-squared error spline transition band fractional delay FIR design to achiev...

This paper introduces new classes of frequency-response masking (FRM) FIR filters. In the FRM approach, the overall filter makes use of periodic model filters and nonperiodic masking filters which makes it possible to obtain FIR filters requiring few arithmetic operations even when the transition band is narrow. A reason for considering the new classes of FRM filters in this paper is that they ...

The double impulse input is introduced as a substitute of the fling-step near-fault ground motion and a closed-form solution of the elastic–plastic response of a structure by the “critical double impulse input” is derived. Since only the free-vibration appears under such double impulse input, the energy approach plays an important role in the derivation of the closed-form solution of a complica...

The multichannel blind deconvolution of finite-impulse response (FIR) or infinite-impulse response (IIR) systems is investigated using the multichannel super-exponential deflation methods (MSEDMs). In the existing MSEDM, the so-called ‘‘second-order correlation method’’ is incorporated in order to estimate the contributions of an extracted source signal to the channel outputs. We propose a new ...

In this paper we design a Finite-Impulse-Response (FIR) filter to enforce the so-called Strictly-Positive-Realness (SPR) condition in an adaptive Infinite-Impulse-Response (IIR) filtering context. The paper results may then be used to guarantee the convergence of pseudolinear regression IIR adaptive algorithms.

In this paper,apracticalIIR@ole-zero)latticeadaptiveaco~tic echo cunceller (AEC) for teleconferencing application is proposed. The proposed algorithm consists in two parts: forward lattice and inverse lattice. Collectively, they are referred to as LATIN (Lattice and Inverse Lattice) configuration. While the forward lattice is responsible for acoustic echo cancellation, the inverse lattice is em...

In this paper, a new two dimensional (2D) adaptive filter structure is developed. It is based on modeling the impulse response of the 2D IIR systems as a finite linear combination of a set of 2D Laguerre orthonormal functions. When long impulse response system is required to identify, computer simulation shows that the 2D Laguerre filter has better performance than the conventional 2D FIR filte...
