TL;DR: In this article, all-pole recursive digital low-pass filters approximating a constant group delay in an equal-ripple sense are described, where the equalripple conditions are given by a system of nonlinear equations in the poles of the transfer function.
Abstract: All-pole recursive digital low-pass filters approximating a constant group delay in an equal-ripple sense are described. The equalripple conditions are given by a system of nonlinear equations in the poles of the transfer function. The closed-form solution obtained for a particular value of the cutoff frequency yields good first approximations for the iterative procedure required in the general case. The set of approximated delays and ripples leading to realizable filters is discussed. Numerical examples illustrating the procedure are included.

TL;DR: A scheme for online monitoring of the LPCs of short-time records of power system signals is developed such that the signal attributes may be displayed in decreasing order of importance but increasing precision.
Abstract: It is shown that finite records of measured power system signals can be exactly modeled or generated by a linear transfer function excited by a unit impulse input. The coefficients of the numerator polynomial and denominator polynomial of the transfer function completely characterize the signal and are called the linear predictive code (LPC). The signal model using the LPC can then be used to compute various signal attributes, such as frequency, the presence or absence of critical modes, the degree of damping, and the amplitude of various signal components, and, most importantly, to predict the future evolution of the signal. A scheme for online monitoring of the LPCs of short-time records of power system signals is developed such that the signal attributes may be displayed in decreasing order of importance but increasing precision. The scheme is evaluated using real-time simulations of various power system oscillations. >

TL;DR: In this article, new validated collector transfer functions are proposed based on a mathematical model that can be found in the literature and has been applied successfully in the field and used for dynamical analysis of collectors and for collector control design.
