Once the output power is ready to use, the Power Good signal tells the digital circuitry that it can begin to operate. Original IBM power supplies for the...

In signal processing, the power spectrum S x x ( f ) {\displaystyle S_{xx}(f)} of a continuous time signal x ( t ) {\displaystyle x(t)} describes the...

is done. PC power supplies often provide a power good signal to the motherboard; the absence of this signal prevents operation when abnormal supply voltages...

−5V, −12V, "power-good signal", and ground. The most notable difference from modern 20/24-pin ATX power connectors is that the AT power supply connector...

electric power, the complexity of a signal box was no longer limited by the distance a mechanical lever could work a set of points or a semaphore signal via...

The Wow! signal was a strong narrowband radio signal detected on August 15, 1977, by Ohio State University's Big Ear radio telescope in the United States...

magnitude of a signal (a time-varying voltage or current). It is a two-port electronic circuit that uses electric power from a power supply to increase...

the power supply voltage is present across the output device at low signal levels. If high output power is needed from a class-A circuit, the power supply...

fields, the color of noise or noise spectrum refers to the power spectrum of a noise signal (a signal produced by a stochastic process). Different colors of...

signal of all: that politicians do not really care about their electorate’s concerns, other than as a device to win and to hold on to their own power"...

Phantom power, in the context of professional audio equipment, is DC electric power equally applied to both signal wires in balanced microphone cables...

couple a defined amount of the electromagnetic power in a transmission line to a port enabling the signal to be used in another circuit. An essential feature...

radio-frequency power amplifier (RF power amplifier) is a type of electronic amplifier that converts a low-power radio-frequency (RF) signal into a higher-power signal...

as good noise immunity (6 dB higher signal-to-noise ratio) as a single-ended system. The main advantage of single-ended over differential signaling is...

sidebands and possibly the carrier signal, which improves the ratio of message power to total transmission power, reduces power handling requirements of line...

Within evolutionary biology, signalling theory is a body of theoretical work examining communication between individuals, both within species and across...

the return path for the signal. As contrasting examples, coaxial cable does, whereas twinax cable does not. High voltage power cables with solid insulation...

In signal processing, white noise is a random signal having equal intensity at different frequencies, giving it a constant power spectral density. The...

low-power signal, or where several circuits must be controlled by one signal. Relays were first used in long-distance telegraph circuits as signal repeaters:...

signal becomes snowy and subject to interference. In contrast, picture quality from a digital television (DTV) signal remains good until the signal level...
