| We have already published designs that use a transistor junction operating in Zener breakdown as a noise source. Anyone who has experimented...
| If a transistor junction operating in Zener breakdown is used as a noise source, the amplitude of the noise signal is asymmetric. This probl...
| 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...
| This circuit is primarily intended to be used by persons who want to experiment with audio. For example, you can determine whether your own...
| 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...
| The fan runs constantly in many PCs, which may not even be necessary. A simple controller circuit can regulate the fan speed according to...
| 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...
| Driven by customer demand, Philips Semiconductor’s AVC Logic family is the fastest logic on the market today and offers ultra low noise an...
| Strictly speaking, noise is a composite of a great number of signals at many, varying frequencies. It is a random quantity which gener...
