The subject of research is methods and means to increase the functionality, accuracy, speed and noise immunity of analog-digital systems (AD-systems) conversion and processing of low-frequency signals through self-calibration of measuring channels, synchronous multichannel reception, data accumulation, electronic scanning, identification of objects using deterministic and fuzzy technologies. Research methods are modeling of processes of collection, amplification, analog-to-digital conversion and multichannel processing of low-frequency signals, recovery and identification of signal sources using neurofuzzy technologies and noise-tolerant coding, layout and experimental studies of devices and software systems. Structures of hardware and software components of multichannel AD-systems of conversion, processing and monitoring of low-frequency signals are developed and technical requirements are formulated. The means of reception, amplification, AD-transformation are investigated. Static and dynamic characteristics of measuring channels are analyzed and new methods of their calibration are offered. Low-noise high-line current signal amplifiers have been studied. Algorithms and programs of multichannel scanning, construction, visualization and recognition of signal sources are developed. Constructions, structural, basic schemes are developed, models and experimental samples of AD-systems are made, their preliminary tests are carried out.
