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 ...

[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 ...

White noise generators commonly are used for testing purposes such as setting the noise level in bit error rate (BER) measurements, providing broadband signals for ...

Zurich, Switzerland—AnaPico has released the APSIN3000 low-noise CW signal generator line. The APSIN signal generators provide optimum signal purity with phase noise as low as -125 dBc/Hz at 1 GHz and ...

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 ...

“Drown out annoying roommates and co-workers today!” says the developer of Noise, a handy little ap for generating pink noise. “Also known as a signal with even power distribution on a logarithmic ...
