28-05-2019 | Some people go to great lengths to generate numbers that are as random as possible. In issue 3 of 2017, we published a design for a Truly Ra...

1-01-2015 | This Function Generator was designed to meet not too ambitious applications and should make a valuable asset in your workspace, at home, or...

4-04-2014 | A simple audio-band noise generator is a useful tool for testing amplifiers. In days gone by, you would use a diode or the base-emitter...

6-05-2013 | Uses Zener diodes to generate avalanche noise signal, then differential amplifier (and a few analog filters) to eliminate deterministic effe...

1-07-2011 | The low dropout voltage regulators from the LM2931 series are not just useful for powering microcontroller systems — they can also act as a...

1-12-2002 | The noise generator proposed here operates according to the digital principle, in contrast with the more classical noise generator, which us...

1-07-2000 | The sound generator shown here uses its built-in loudspeaker as a microphone when it is in the standby state. As soon as it detects a noise...

1-03-1999 | Strictly speaking, noise is a composite of a great number of signals at many, varying frequencies. It is a random quantity which gener...

1-11-1996 | Circuits for making audible sound effects stored in an rc are nothing special any more these days. A disadvantage of many of them is,...

1-07-1992 | Noise generators are used for measuring the self-noise of amplifiers and receivers and for same acoustic measurements. The noise of tradi...
