Noise in electrical circuits is typically the enemy, and any self-respecting circuit should output as little noise as possible. Nevertheless, there are cases where a well-characterized source of noise ...

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 ...

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 ...

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 ...
