Noisesources.com The website that helps you sort through the confusion of what noise sources are available for a particular application.
Noise Sources have a very wide range of applications for improving electronic communications. As a result, there are many types ranging from Microwave coaxial and waveguide sources to small surface mount noise sources for encryption and built in test. In fact there are nine distinct common usages for noise. There are also several other less common applications. Noise Applications gives you a brief overview of the big nine.
This website helps to select the proper noise source for a given requirement thus saving the designer the cost of having to use unneeded extra components. There are many ways to sort through the varied maze of noise source types. We will sort primarily by examining each of the seven applications in detail. Through this process, it will be easier for the designer to specify the attributes for their particular needs.
All solid-state noise sources have as their engine a noise diode. When biased properly the noise diode puts out white Gaussian noise over a certain frequency range. The term "White" means that the amplitude is even or flat across the spectrum. The term Gaussian means that the probability density function is random and follows a bell curve. The raw noise diode needs biasing circuitry to produce the noise. The output specifications of the noise circuit are dependent on two variables, the characteristic of the noise diode itself and the biasing circuit. The ability to shape the noise amplitude spectrally is an art as much as it is science in that the years of collective experience helps a design team immensely for producing a desired output. No modeling software is available unlike more mainstream microwave component designs that have modeling software available.
