11Power-on self-test — Le Power on self test (POST, l auto test au démarrage) désigne la première étape du processus plus général appelé amorçage. Lors de cette étape, le programme intégré à la carte mère (le BIOS pour Basic Input/Output System ) teste la présence des… …
12Power factor — For other uses, see Power factor (pistol). The power factor of an AC electric power system is defined as the ratio of the real power flowing to the load over the apparent power in the circuit,[1][2] and is a dimensionless number between 0 and 1… …
13Power network design (IC) — In integrated circuits, electrical power is distributed to the components of the chip over a network of conductors on the chip. Power network design (IC) includes the analysis and design of such networks. As in all engineering, this involves… …
14Power supply — For the Budgie album, see Power Supply (album). A vacuum tube rackmount adjustable power supply, capable of +/ 1500 volts DC, 0 to 100mA output, with amperage limiting capability. A power supply is a device that supplies electrical energy …
15Power gain — The power gain of an electrical network is the ratio of an output power to an input power. Unlike other signal gains, such as voltage and current gain, power gain may be ambiguous as the meaning of terms input power and output power is not always …
16Input impedance — The input impedance, load impedance, or external impedance of a circuit or electronic device is the Thévenin equivalent impedance looking into its input.In audio systemsGenerally in audio and hi fi, the input impedance of components is several… …
17Power-on reset — A power on reset (PoR) generator is a microcontroller or microprocessor peripheral that generates a reset signal when power is applied to the device. It ensures that the device starts operating in a known state.In VLSI devices, the power on reset …
