“…The calculations of the bit resolution of our system will be done in terms of metastability of analog digital converters [58]. The conversion time is due to the settling of the input signal or mismatching [59].…”

This work presents a novel architecture, exemplified for electrophysiological applications like ECoG that can be used to detect Epilepsy. The new ECoG is based on a mixed analog-digital architecture (Pulse Amplitude Modulation PAM), that allows the use of thousands of electrodes for recording. Whilst the increased number of electrodes helps to refine the spatial resolution of the medical application, the transmission of the signals from the electrodes to an external analysing device appears to be a bottleneck. To overcoming this, our work presents a hardware architecture and corresponding protocol for a mixed architecture that improves the information density between channels and their signal-to-noise ratio. This is shown by the correlation between the input and the transmitted signals in comparison to a classical digital transmission (Pulse Code Modulation PCM) system. We show in this work that it is possible to transmit the signals of 10 channels with a analog-digital architecture with the same quality of a full digital architecture.

“…Thus, to improve the SC reliability, the topical issue of TCS's EDP diagnostics based on the continuous monitoring of the electromechanical section's parameters should be solved ensuring identification of the residual operating life, as well as functional and parametric failure (Budanov et al, 2017;Davydov et al, 2017;Repin and Valdman, 2018). The current work objective is review of the diagnostic methods of drives based on synchronous motors with permanent magnets, as well as substantiation of the monitoring parameters's choice and formation of functional scheme of the EDP's diagnostic system.…”

Modern diagnostics methods ensuring the safety of production and operation, as well as the improvement of functional characteristics of electromechanical systems’ are discussed, method of diagnostics according to the spectrum and hodograph of the engine’s equivalent current is presented. Functional concept is presented for the system of control, diagnostic and monitoring of technical condition of thermal control systems’ electromechanical part in the spacecraft. The decision-making and forecasting algorithm for the operational resource is based on ground-based studies and diagnostic results. This approach to device diagnostics and monitoring is also used in other servo drives, mechatronic and robotic systems of space vehicles and other objects that are inaccessible and left unattended. Hardware-algorithmic implementation of the system is described, recommendations on the components base selection are given.

A method is proposed to significantly increase the dynamic range of current and voltage meters in the traction networks of railway transport. The method is based on the low entropy of signals of this type and is based on the calculation of samples whose amplitude was distorted due to the output beyond the ADC dynamic range. The approach with the solution of system of linear equations is considered. An approach without solving a system of linear equations is presented. The accuracy of the method is discussed at the end of the article.
