The subject of noise is vast and volumes have been devoted to it. Therefore, it is important that we restrict our coverage of the subject and concentrate on the more essential basics.
The goal of this article is to present a clear picture of important measurement parameters that relate to random noise. This article will concentrate to the study of random noise of the types generated by resistors, diodes, active components ect. This is essential for gaining good understanding of noise measures such as “Noise Factor”. We will concentrate only on the properties of random noise and its measurement. Only the amplitude characteristics and measures of noise will be considered in this article.
