Noise Source Predominance Map: a new representation for strategic noise maps

A Modified Noise Analysis of a Common Source ̶ Common Gate Low Noise Transconductance Amplifier for Sub-micron Technologies

This paper is based on analysis of a common source - common gate low noise transconductance amplifier (CS-CG LNTA). Conventional noise analyses equations are modified by considering to the low output impedance of the sub-micron transistors and also, parasitic gate-source capacitance. The calculated equations are more accurate than calculated equations in other works. Also, analyses show that th...

A Flexible Noise Model For Designing Maps

In this paper, we propose a flexible noise model for multi-dimensional map synthesis. This model allows the generation of a very varied range of maps, that can be used as perturbation functions, for the generation of color textures, or as bump or displacement maps, for geometric deformation of surface or volume objects. We demonstrate that, because the noise construction is random and procedura...

Transient Noise Source Localization

Conventional beamforming systems for noise source localization are mostly based on frequency domain calculations. Additionally, narrowband assumptions concerning signal characteristics are often made to simplify the calculations, i.e. to be able to express a single time delay as a sole phase shift in the frequency domain as well. If necessary, a broadband system is then modeled as a composition...

Creating noise pollution maps based on user-generated noise measurements

Environmental pollution has become a rising concern during the last decades. Especially in big cities with their huge traffic volume, the pollution by the generated noise has become an imminent health threat to the citizen [40]. To protect their citizens, states in the EU have agreed on a directive which forces them to curtail the threat that is noise pollution [31]. First and foremost, this gi...
