NAND. A logic function of A and B that is true if either A or B is false.
NAND CIRCUIT. A combination of a NOT function and an AND function in a binary circuit that has two or more inputs and one output. The output is logic 0 only if ALL inputs are logic 1; it is logic 1 if ANY input is logic 0.
NATURAL FREQUENCY. See RESONANT FREQUENCY.
NATURAL HORIZON. The line-of-sight horizon.
NAUTICAL RADAR MILE. See RADAR MILE.
NEAR SYNCHRONOUS ORBIT. An orbit in which the satellite rotates close to but not exactly at the
same speed as the earth.
NEGATION. The process of inverting the value of a function or variable.
NEGATIVE ALTERNATION. That part of a sine wave that is below the reference level.
NEGATIVE CLAMPER. A circuit that clamps the upper extremity of the output waveshape to a dc
potential of 0 volts.
NEGATIVE ELECTRODE. A terminal or electrode having more electrons than normal. Electrons flow
out of the negative terminal of a voltage source.
NEGATIVE FEEDBACK. Feedback in which the feedback signal is out of phase with the input signal.
Also called DEGENERATIVE FEEDBACK.
NEGATIVE LOGIC. The form of logic in which the more positive voltage level represents a logic 0,
FALSE, or LOW and the more negative voltage represents a logic 1, TRUE, or HIGH.
NEGATIVE-RESISTANCE ELEMENT. A component having an operating region in which an increase
in the applied voltage increases the resistance and produces a proportional decrease in current.
Examples include tunnel diodes and silicon unijunction transistors.
NEGATIVE TEMPERATURE COEFFICIENT. A characteristic of a semiconductor material, such as
silver sulfide, in which resistance to electrical current flow decreases as temperature increases.
NETWORK. A combination of electrical components. In a parallel circuit it is composed of two or more
branches.
NEUTRAL. In a normal condition, hence neither positive nor negative. A neutral object has a normal number of electrons (the same number as protons). A current-carrying conductor normally tied to ground so that the electrical potential is zero. .
NEUTRALIZATION. The process of counteracting or "neutralizing" the effects of interelectrode capacitance.
NEWTON'S SECOND LAW OF MOTION. If an unbalanced outside force acts on a body, the resulting acceleration is directly proportional to the magnitude of the force, is in the direction of the force, and is inversely proportional to the mass of the body.
NODE. The fixed minimum points of voltage or current on a standing wave or antenna.
