The results of NI LabVIEW digital modeling of application of the α-trimmed mean to suppress industrial interferences in the process of analog-to-digital conversion are presented. The stability of the ADC bit-for-bit encoding with different weighting factors (binary, Fibonacci codes) to periodical interference, impulse interference and normal noise is estimated. It is established that the drop 5–15%...
In this article a new technique of process variation estimation in electrical circuit is presented. Technique is based on interval analysis application for a ladder circuit. Using this particular class of electrical circuit high speed of calculation could be achieved which is important in optimization and automated synthesis. In the article general ability of the technique application for a resistor...
Resistive gas sensors based on the SiO2SnOx-CNT nanocomposite thin film are designed. Films are prepared by sol-gel technique from Tetraethoxysilane solutions with addition of tin and CNT compounds. It is established that the SiO2SnOx-CNT films possess semiconductor properties. Produced gas sensors are sensitive to nitrogen dioxide at low (<50°C) operating temperatures. X-ray spectroscopy (XPS)...
This work considers the task to determine the number of classes for a rank-based image thresholding algorithm. A new approach is proposed, which is based on a rank histogram ensemble forming. Rank histograms are considered as linear space vectors, for which the orthonormal basis dimension is determined using the modified Gram-Schmidt process. The histogram bar height distribution is considered for...
In the present work on the base of modified energy approach a behavior of the frequency-dependent coupling coefficient of pair microstrip stepped-impedance quarter-wavelength resonators was investigated. It is revealed that at a certain gap between the resonators the total coefficient of coupling becomes zero due to mutual compensation of coefficients describing inductive and capacitive interactions...
