Kryshtal R. G., Kundin A. P., Medved A. V., et al. Liquids recognition by means of a sensor on surface acoustic waves of shear-horizontal polarization

 

Basic possibility of recognition of liquids by means of the single sensor on surface acoustic waves with shear-horizontal polarization is shown experimentally. No multi element sensor arrays were used in our work in contrast with the convenient recognition methods used in electronics nose or electronics mouth systems. Pulse characteristics measured at actions of some liquids are presented thus showing working capacity of the proposed sensor. Some experimental data demonstrating high enough reproducibility of measurement results is given. Some possibilities of application of molecularly imprinted polymers as selective layers in our sensors are discussed.

Keywords: liquids sensor, surface acoustic waves with shear-horizontal polarization, piezoelectric, sensors array, molecularly imprinted polymer, selectivity, morpholin, inverse fast Fourier transform, S-parameters.

Avanesyan H. R. An evaluation of frequency distortions of random signals by a method of a comparison of their autocorrelated functions

 

In the article the method permitting to determine a frequency distortions of signals in circuits, located in a working mode both switching-off not supposing them and translation in a test mode is circumscribed. The method is based on a comparison of the correlation characteristics of random signals which are operational on an input and an output of a circuit. The criterion of detection and evaluation of frequency distortions of random signals have normal distribution is offered. The features of a method are considered.

Keywords:  distorsions, correlation, signal, spectrum.
