White-noise generators generate a flat graph of output-power density versus frequency. These generators are useful for testing circuits that have an extended low-frequency or dc response. However, the ...

The behavior of analog circuits can often be characterized by sweeping their inputs with a signal going across a range of frequencies and then observing the output. These sweeps can be composed of ...

A design idea for a white-noise generator is realized and revised. Two low-noise amplifiers (LNAs) in cascade amplify the noise produced by a reverse-biased Zener diode operating in junction-breakdown ...

Using an 8-pin PSoC to Produce 100Khz Pseudo Random White Noise with a Six Hour Period By using the programmable blocks of a Cypress MicroSystems CY8C25122 PSoC microprocessor, it is possible to ...

[Jordi] made this awesome looking mini amplifier which has a rather unusual feature. He’s calling it the Bizarre Mini Amplifier because it also has a white noise generator built right into it! Bizarre ...

Around 1990, Chattanoogan Sam Hall and his wife bought a mechanical white-noise generator to help them sleep after a neighbor's dog began yapping incessantly at night. Mark Kennedy is a veteran ...

A random noise generator is pretty handy when working with music, and building one using a micro-controller can be pretty trivial. So it’s nice when someone comes along and builds it from a few analog ...
