1-11-2004 | Quartz oscillators are the way to go when you need a precise, stable frequency source but what do you do when an application calls for a non...

1-11-2004 | In the three-part article for the ClariTy 2 x 300-W final amplifier, the various input and output filters were not described. In this articl...

1-12-2003 | Many radio signals in the medium and long wave bands (MW/LW) but also shortwave (SW) are infested by noise of wide variety and of such level...

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...
