H
HEXADECIMAL SYSTEMPertaining to the number system with a radix of sixteen. It uses the ten digits of the decimal system and the first six letters of the English alphabet [13]. |
HIGH FREQUENCYThe band of frequencies from 3 megahertz to 30 megahertz [17]. |
HIGH-FREQUENCY COMPENSATIONSee PEAKING COIL [8]. |
HIGH-PASS FILTERA filter that passes a majority of the high frequencies on to the next circuit and rejects, or attenuates, the lower frequencies. Also called a LOW-FREQUENCY DISCRIMINATOR [9]. |
HITS PER SCANThe number of times an RF beam strikes a target per antenna revolution [18]. |
HOLE FLOWIn the valence band, a process of conduction in which electrons move into holes, thereby creating other holes that appear to move toward a negative potential. (The movement of holes is opposite the movement of electrons.) [7] |
HORIZONTAL AXISOn a graph, the straight line axis that is plotted from left to right [10]. |
HORIZONTAL PATTERNThe part of a radiation pattern that is radiated in all directions along the horizontal plane [10]. |
HORIZONTAL PLANEAn imaginary plane that is tangent (or parallel) to the earth's surface at a given location [11] [18]. |
HORIZONTAL-DEFLECTION PLATESA pair of parallel electrodes that moves the electron beam from side to side in a CRT [6]. |
