Engineering Physics Annotation << Back REJECTOR AUTOCOMPENSATION OF FEEDBACK IN SYSTEMS AND INSTALLATIONS OF SIGNAL RADIO ACOUSTICS N.R. LEVCHENKO, D.I. SHILINGOVSKY The article deals with the analysis of software and hardware methods for suppressing electro-acoustic feedback in radio-electronic systems for audio monitoring and television production. The paper presents a numerical analysis of signal methods for positive feedback compensation (PFC) of radio acoustics, as well as an architectural DSP solution for constructing a notch equalization line with auto-tracking multi-tone sound suppression based on the ADAU1701 audio processor and the SigmaStudio development software package in problems of auto-compensation of electroacoustic PFC when creating experimental physical installations. signal radio acoustics. Methods: algorithms of digital signal processing, theory of stability of sound-amplifying and sound-picking radio systems, methods of signal radio acoustics, theory and methods of analysis of self-oscillating circuits, vector theory of the sound field. Results: the causes of electroacoustic feedback have been identifi ed; an adaptive algorithm for suppressing electroacoustic feedback has been proposed and investigated; an experiment with the use of an electroacoustic feedback auto-suppression submodule has been analyzed. Keywords: signal radio acoustics, electroacoustic feedback, feedback suppressor, radio electronic audio monitoring system. DOI: 10.25791/infizik.7.2023.1341 Pp. 15-21.
