Моноиммитансный логический R-элемент «И»

Abstract

This paper deal with the logical monoimmittance R­element "AND", using active immittance as a information parameter. There are mathematical model and truth table of the R­monoimmittance logic element "AND" received in this article. The effect of destabilizing factors on the characteristics of the logical monoimmittance R­element "AND" such as the instability of the wave resistance of the transmission line, the emergence of the transmission line segments length and the emergence of parasitic reactance in the input immittance is researched. The results showed that the change in the wave resistance of the transmission line does not affect on operation of the circuit. Changing of the input reactive impedance in the range of 0 ­ 10 ohms linearly affects to the reactive impedance output, the output active impedance does not vary more than 2% and is within the logic levels "0" and "1". With error of the transmission line length in 0...1,0 mm output active impedance does not vary more than 2% and is within the logic levels "0" and "1", the output reactive impedance varies linearly. Noise immunity of monoimmittance R­logic element "AND" has a value of at least 0.98 in all these cases.
