Using a single op amp and a properly selected resistor, this white-noise generator provides flat output versus frequency and speeds testing of circuit performance. The behavior of analog circuits can ...

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 ...

[Hans] wanted to see the frequency response of a bandpass filter but didn’t have a lot of test equipment. Using an RTL-SDR dongle, some software and a quickly made noise generator, he still managed to ...

More advanced systems are becoming autonomous and location-aware, placing greater demands on timing subsystems, including ...

I sometimes need a noise generator for testing equipment, and useful signals must often be mixed with the noise, such as when testing equipment designed to extract a clean signal from a contaminated ...

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 ...
