Digital signal processing in real time in multi signal monitoring systems with high risk of application

Article considers the establishing requirements of digital signal processing in real-time systems with high risk of application on which execution the system has added by signs of safe system. In addition, article considers the analysis of a technical solution for the analog front end (AFE) for multi signal system and based on results of analysis designed a node of signals preprocessing in paralleled channel. Creation of AFE in relation to multi signal systems is considered. Article contains results of multi signal analysis and testing results of the specialized diagnostic measuring tool for the multi signal monitoring system used in railway automatic.
