Resonance filtration by two-phase resonators
Introduction. Resonance spectral filtration has an exceptional importance for many applica-tions. Resonators based on reflectors with antiphase reflection coefficients — two-phase res-onators — are proposed. Single-phase...
Research of ambiguity function of discrete ten-element frequency manipulation sygnal
Ambiguity function of a discrete frequency signal in which the number sequence «Welch-10» as frequency coding sequence is used is considered.
Influence of the Matrix Structure of the Modulator and Detector on the Optical Spectrum Analyzer Output Signal
In this article, we investigate the physical and mathematical model of a coherent optical spectrum analyzer (COSA), which uses a matrix light modulator and a matrix detector as input and output devices. This model allows...
Analysis of structure of quasi-optimal strategy for optimization of analog circuits
Application of optimal control theory allowed generalizing methodology of analog circuit optimization. The problem of search of minimum at times strategy of circuit optimization is formulated as a classic problem of opti...
