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 ...

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 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 ...

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 ...

An adjustable white noise generator is a handy tool that can be used to examine the circuit or a communication line under some random noises to make sure about the stability of the device in real and ...

[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 ...
