Random numbers are useful beasts, in particular for cryptographers who use them to generate their codes. But how best to make random numbers at useful speeds? The question is intimately linked to the ...

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 ...

Phase noise is the result of small random fluctuations or uncertainty in the phase of an electronic signal. We specify and measure phase noise because it is a fundamental limitation in the performance ...

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 ...

Two years ago we featured SimplyNoise, a dead-simple white noise generator. A recent update adds in additional sounds, features, and an iOS app for white-noise naps on the go. Originally SimplyNoise ...

Quantum physics can be exploited to generate true random numbers, which have important roles in many applications, especially in cryptography. Genuine randomness from the measurement of a quantum ...

Noise generators are very useful devices. They are used in test equipment, random number generators, etc. Usually, designers use special Zener noise diodes (at very low current) and transistors (with ...
