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 ...

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 ...

A common PC sound card can be used as a sine/square/triangle function generator, but the output suffers from limited rail-to-rail swing, plus its zero-centered has no dc offset. This circuit overcomes ...

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 ...

Part 1 of a two-part series on RF signal generators. Gain a sound understanding on the fundamental specifications of signal generators. June 22nd, 2022 - By: Keysight Eliminate uncertainties and ...

A random noise generator is pretty handy when working with music, and building one using a micro-controller can be pretty trivial. So it’s nice when someone comes along and builds it from a few analog ...
