Noise generator

Noise generators are used for measuring the self-noise of amplifiers and receivers and for some acoustic measurements. The noise of traditional low-frequency noise generators is based on the stochastic properties of an ion current resulting from a gas discharge. A simple noise generator can, however. be designed without a special gas discharge tubes the reverse-biased[…]

Crowbar Protection

Quite a few electronic components. particularly active ones. cannot withstand too high voltages. Preventing costly circuits dying a premature death because the supply voltage has risen too high makes overvoltage protector no luxury. Such a protector must, of course, act swiftly, otherwise, the deed has been done before it had a chance to act. Therefore.[…]
