The adaptive equalization of frequency characteristic of systems by the IIR filter is analyzed. Comparative results of application for the least squares method and sequential regression method are presented.
Signals recorded by seismic sensors, formed by the superposition of seismic waves propagating in the ground by multipath paths. Therefore, they obey a Gaussian distribution, and spectral-correlation properties allow the use of Markov models based on recurrent linear prediction mechanism. Models of this type are used in various fields, such as processing of speech signals, sonar systems, as well as...

The problem of regulation for a DC motor with autonomous voltage inverter is discussed. The considered control system consists of two feedback loops. In the first one, the armature current control for a DC motor is provided by means of pulse-width modulated control of autonomous voltage inverter. In the second one, DC motor speed control is maintained. Proportional-integral (PI) controllers are designed...
In this paper, the parametric and nonparametric approaches to construction of probabilistic reliability model with one-shot device testing data are considered. Such data are referred to as current status data, which include right censored and left censored observations (no complete observations at all). Statistical properties of maximum likelihood estimates of distribution parameters have been investigated...
