Does anyone know how to rig up a simple white noise generator? A coworker needs one to do a frequency response measurement and needs it from ~100 Hz up to 100 kHz. We can get to Radio Shack (or order ...

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 ...
