Bases of construction of optoimmittance logic are formulated, marketability’s of optoimmittance logical elements are considered, that will allow extending functional possibilities and improving the technical parameters of different informative devices. The classification, technical implementation, the basic parameters and characteristics of optoimmitance logical elements are presented. The speed of optoimmittance logical elements is analyzed.
In the paper a filter on the parallel resonant circuit on L-, C-negatrons is suggested. The parallel resonant circuit on L-, C-negatrons is investigated. Stability of the contour and frequency characteristics are considered. Experimental researches of the contour on the circuitry analogues of negatrons are conducted. Use of L-, C-negatrons improves the frequency-selective properties of the filter. Simulation of the filter on circuitry analogues of L-, C-negatrons on operational amplifiers LF400C is done. The simulation results showed improvement of frequency selectivity of the filter characteristics by reducing the phase distortion.
