The subject of the study is a system for collecting and processing biophysical signals for controlling anthropomorphic prostheses. As a result of the work, structural and electrical circuits for measuring biophysical signals, processing and filtering schemes were proposed, and the necessary filters were calculated. Designed filters allow you to get rid of noise caused by artifacts of movements and your own signal instability, and can be used to design a system for collecting and processing electromyography signals. In conjunction with a digital filtering system and further processing, it is possible to adequately determine the presence of muscle contractions. The resulting system is small-sized and in combination with the software part of signal processing will allow you to determine key signal patterns and control anthropomorphic prostheses.
