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 ...
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 ...
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 ...
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 ...
