DIRECT CURRENTAn electric current that flows in one direction only [1]. | |
DIRECT SHORTSame as SHORT CIRCUIT [3]. | |
DIRECTIONAL ANTENNAAn antenna that radiates most effectively in only one direction [18]. | |
DIRECTIONAL COUPLERA device that samples the energy traveling in a waveguide in one direction only [11]. | |
DIRECTIVITYThe ability of an antenna to radiate or receive more energy in some directions than in others. The degree of sharpness of the antenna beam [10] [11] [18]. | |
DIRECTLY HEATED CATHODEA wire, or filament, designed to emit the electrons that flow from cathode to plate. The filament is designed so that a current is passed through it; the current heats the filament to the point where electrons are emitted [6]. | |
DIRECTORThe parasitic element of an array that reinforces energy coming from the driver element [10]. | |
DISCRETE COMPONENTSIndividual transistors, diodes, resistors, capacitors, and inductors [14]. | |
DISCRIMINATORA circuit in which amplitude variations are derived in response to phase or frequency variations [18]. | |
DISPERSIONThe refraction of light waves that causes the different frequencies to bend at slightly different angles [10]. | |
