NOISE: Measurement and Generation
نویسنده
چکیده
It is difficult to improve something unless we are able to measure it. Measurement of noise in receivers does not seem to be clearly understood by many amateurs, so I will attempt to explain the concepts and clarify the techniques, and to descrive the standard “measure of merit” for receiver noise performance: “noise figure.” Most important, I will describe how to build your own noise generator for noise figure measurements.

Vehicles and Noise Pollution Measurement and their Effects on Public and Mental Health on Qom Citizens
One of the most important issues in today&rsquos urban world is increasing use of cars and its noise pollution, which is now one of the most important affecting pollutants on health and quality of lives of residents in urban areas. Noise pollution effects on various aspects of human and the community health as well as the high cost of treatment, thus more studies in this field is needed. Hence ...
متن کاملAn Intelligent Anti-Islanding Scheme for Synchronous-Based Distributed Generation Using Reduced-Noise Morphological Gradient
This paper presents a pattern recognition-based scheme for detection of islanding conditions in synchronous- based distributed generation (DG) systems. The main idea behind the proposed scheme is the use of spatial features of system parameters such as the frequency, magnitude of positive sequence voltage, etc. In this study, the system parameters sampled at the point of common coupling (PCC) w...
متن کاملDetecting pitting corrosion and its severity using wavelet entropy in electrochemical noise measurement
Entropy as a measure of uncertainty was used to represent the results of the wavelet technique in electrochemical noise analysis. The experimental signals were obtained by recording the electrochemical potential and current noise of 7075 aluminum alloy in 3.5% NaCl solution. The electrochemical potential and current noise were decomposed into 16 levels using Daubechies wavelets. Wavelet output ...

متن کاملNumerical Simulation of Random Irregular Waves for Wave Generation in Laboratory Flumes
Understanding of wave hydrodynamics and its effects are important for engineers and scientists. Important insights may be gained from laboratory studies. Often the waves are simulated in laboratory flumes do not have the full characteristics of real sea waves. It is then necessary to present reliable methods of wave generation in wave flumes. In this paper, the results of numerically simulate...
