The paper considers a task of processing measurements to determine the state vector of a dynamic object, for example, an aircraft. A linear discrete filtering algorithm based on the Kalman filter is proposed. It is capable of modifying its structure using fuzzy expert system depending on the intensity of the object maneuver. The performance and efficiency of the algorithm are confirmed by the results of numerical simulation.

The possibility of synthesis of ultra-fast universal optical digital-to-analog converter (DAC) providing conversion of digital information into analog information in giga- and terahertz ranges, including in digital systems based on N-digit logic, is considered. The functional diagram of the optical DAC containing technologically well-developed optical elements is given, the principle of operation is described in detail. The possibility of implementing this DAC with the speed potentially possible for optical data processing circuits is shown.
