In this paper, digital analyzer of diamond detector signals of ITER Vertical Neutron Camera (ITER VNC) are described, which uses digital signal processing. Digital analyzer of pulse signals is based on ADC12500PXIe (two channels, 12 bit, 500 MHz, PXI Express), which satisfies the ITER VNC requirements. In this paper, the architecture of digital signal processing unit is given. Trapezoidal digital shaper for pile-up separation and energy spectrum unit are described. In addition, structure of digital analyzer software levels are considered

n order to detect anomalies and improve the quality of forecasting dynamic data flows observed from sensors in Industrial Control System (ACS)., it is proposed to use a predictive mod-ule consisting of a series-connected digital signal processing unit (DSP) and a predictive unit using a neural network (predictive autoencoder ( Auto Encoder), predictive Autoencoder (PAE)). The study showed that the preliminary DSP block of the predicted input signal, consisting of a parallel set (comb) of digital low-pass filters with finite impulse responses (FIR-LPF), leads to a non-equilibrium account of the correlation relationships of the time samples of the input signal and to increase the accuracy of the final prediction result. The predicted autoencoder (PAE) pro-posed and considered in the work, in addition to restoring the input signal or part of the input signal at the PAE output, also generates the predicted samples of the input signal for the speci-fied number of «forward» time steps at the output, which increases the accuracy of the predic-tion result. The reduction of the forecast error occurs due to the imposition of restrictions in the formation of the forecast, that is, an additional requirement to restore the input samples of the samples – «stabilizers» at the NS output. The introduction of «stabilizers» increases the accuracy of the prediction result.

In this paper, we propose a remote 3-D displacement measurement method using the radio wave for indoor shaking table facilities. It also shows the effectiveness of the proposed method by some radio experiments using a shaking table. The proposed measurement system consists of simple transmitters attached to each reference point and several receiving antennas at different places connected with a digital signal processing unit. The locations of the transmitters are simultaneously estimated by observing the phase differences between signals at receiving antennas. This prototype radio experimental system consists of 3 transmitters of frequency 2.45GHz, 4 receiving antennas and a microcomputer. We made the demonstration for the reconstructions of the 0.1Hz and 2Hz sinusoidal excitations at 3 reference points of the testing structure on the shaking table. The accuracy of estimated displacement was several centi-meters to several mili-meters.

<span>Dramatic rises in power density and die sizes inside system-on-chip (SoC) design have led to the thermal issue. High temperatures or uneven temperature distributions may result not only in reliability issues, also has become the biggest issue that can limit the system performance.  This paper presents the design and simulation of a temperature-based digital signal processing unit for modern system-on-chip design using the Verilog HDL. This design provides continuous monitoring of temperature and reacts to specified conditions. The simulation of the system has been done on Synopsys Software. The result showed that temperature monitoring process is within the temperature range due to the incorporation of an interrupt-based system and with an advantage of minimum chip area required.</span>

CVD Diamond Detectors are going to be used in a number of neutron diagnostics of the International Thermonuclear Experimental Reactor (ITER) during its power operation phase [1]. One of such diagnostics is the Vertical Neutron Camera (VNC), which is being developed by the ITER Russian Domestic Agency (Institution “Project Center ITER”). In VNC Diamond detectors are used for real-time neutron flux and neutron spectrum measurements. In this paper we present current advancements in the development of a digital signal processing unit for the VNC diamond detector measurement channel. We give an overview of the signal properties, hardware requirements and firmware/software solutions used in the current version of the signal processing unit. We also present preliminary test results for this measurement system and explain the discovered problems and possible solutions.
