Electrical Definitions |
NAND Gate : (1) An AND gate to which has been added an inverted output. (2) A gate that is enabled when both its inputs are present or high. |
Natural Frequency : The frequency,at which free oscillations occur in an electrical or mechanical system. It is the frequency at which resonance occurs in such a system in response to a periodic driving force. |
Neon Tube Rectifier : A rectifier consisting of a tube contaning neon at a low pressure with special shaped electrodes not independently heated,in some cases provided with grid control. |
Network : A system consisting of a number of impedances or sub assemblies connected together to perform specific function. |
Negative Logic : The system of logic in which a low represent a 1 and a high represent 0. |
Noise Bandwidth : The noise bandwidth of a network is the area divided by the height,at the centertuned frequency of the power gains vs frequency characteristics. |
Noise Margin(dc) : The dc noise margin of a logic gate is a measure of noise immunity i.e.the capacity of the gate to withstand fluctuations of the voltage levels (noise) at its output. |
NOR Gate : An OR gate to which has been added an inverter at its output. A combination of a NOT and OR circuit. |
NOR Circuit : A binary circuit having a single input and a single output in which the output is always the opposite of the input.When the input is on(1) the output is off(0) and vice versa.This circuit is also called an inverter circuit. |
