1-09-2003 | The circuit described here is used to control the acoustic noise levels produced in a room or office. The main idea behind installing the de...

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

1-12-2000 | If a transistor junction operating in Zener breakdown is used as a noise source, the amplitude of the noise signal is asymmetric. This probl...

1-12-2000 | We have already published designs that use a transistor junction operating in Zener breakdown as a noise source. Anyone who has experimented...

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...

1-07-2000 | This circuit is primarily intended to be used by persons who want to experiment with audio. For example, you can determine whether your own...

1-07-2000 | The signal from a microphone is two weak for a standard line input. This low-noise DC-coupled microphone amplifier provides a solution for a...

1-12-1999 | The fan runs constantly in many PCs, which may not even be necessary. A simple controller circuit can regulate the fan speed according to...

1-07-1999 | Driven by customer demand, Philips Semiconductor’s AVC Logic family is the fastest logic on the market today and offers ultra low noise an...

1-07-1999 | If, like many other people, you have ever been annoyed by the noise of, say, the extractor fan in your bathroom, here’s a tip that may q...
