HEXADECIMAL SYSTEM

Pertaining 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 FREQUENCY

The band of frequencies from 3 megahertz to 30 megahertz [17].

HIGH-FREQUENCY COMPENSATION

See PEAKING COIL [8].

HIGH-PASS FILTER

A 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 SCAN

The number of times an RF beam strikes a target per antenna revolution [18].

HOLE FLOW

In 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 AXIS

On a graph, the straight line axis that is plotted from left to right [10].

HORIZONTAL PATTERN

The part of a radiation pattern that is radiated in all directions along the
horizontal plane [10].

HORIZONTAL PLANE

An imaginary plane that is tangent (or parallel) to the earth's surface at a given
location [11] [18].

HORIZONTAL-DEFLECTION PLATES

A pair of parallel electrodes that moves the electron beam from side to side in a CRT [6].
