Modern train interval control systems contain communication channels between traffic organizers and the locomotive, using rail inductive as lines. The threads that make up these lines are an integral part of traction network and, therefore, current is channeled through them. Bearing this in mind, signals operate under conditions strong interference from current. At present, continuous automatic...

The placement of substrate contacts in epi and non-epi technologies is analyzed in order to control and reduce the substrate noise amplitude and spreading. The choice of small or large substrate contacts or rings for each of the two major technologies is highlighted. Design guidelines for placing substrate contacts so as to improve the noise immunity of digital circuits in mixed-signal smart-po...

To improve the performance of atomic force microscopes regarding speed and noise sensitivity, it is important to consider the mechanical rigidity of the actuator (scanner), and the overall mechanical structure. Using finite element analysis in the design process, it was possible to increase the first resonance frequency from 950 Hz for the whole system to 23.4 kHz for the whole system. This con...

Chaotic systems are widely used to detect the weak signal of the noise background. The effect of the noise in the detection is often ignored because of the characteristics of sensitive to certain signals and inert to noise. However, it's found that chaotic system has low noise immunity for some different variance of noise after a large number of experiments, which makes mistake for the signal t...

In the near future of high component density and low-power technologies, soft errors occurring not only in memory systems and latches but also in the combinational parts of logic circuits will seriously affect the reliable operation of integrated circuits. This paper presents a novel design style which reduces the impact of radiation-induced single event transients (SET) on logic circuits, and ...

Electronic communications devices that operate in environments with a high level of electromagnetic noise require special consideration and testing to ensure the continuous delivery of uncorrupted data. Communication devices are susceptible to data interruption and corruption in industrial, automotive, telecommunication, medical and test lab environments, to name just a few. Demonstrating compl...

In recent years power saving is one of the important thing. Domino logic circuit is power efficient cicuit,so it is widely used in variety of applications in digital design. But it has a limitation of low noise immunity and more leakage current. This problem can be solved by using keeper transistor to compensate leakage current of pull down network. The conventional keeper domino circuit reduce...

This paper investigates several configurations for placing electrodes on a 3D cylindrical medium to reconstruct 3D images using 16 electrode EIT equipment intended for use with a 2D adjacent drive protocol. Seven different electrode placement configurations are compared in terms of the following figures of merit: resolution, radial and vertical position error, image magnitude, immunity to noise...
