TRANSISTOR. A semiconductor device with three or more elements. [BJT Manufacturers]
TRANSITION. The time it takes to shift from a mark to a space condition or from a space to a mark condition.
TRANSIT TIME. The time an electron takes to cross the distance between the cathode and the plate.
TRANSLATION. In a gyro, a force acting through the center of gravity of the gyro that causes no torque on the gyro rotor. Translation forces do not change the angle of the plane of rotation but move the gyroscope as a unit.
TRANSLUCENT. Those substances, such as frosted glass, through which some light rays can pass but through which objects cannot be seen clearly.
TRANSMISSION LINE. A device designed to guide electrical or electromagnetic energy from one point to another.
TRANSMISSION MEDIUM. A means of transferring intelligence from point to point; includes light, smoke, sound, wire lines, and radio-frequency waves.
TRANSMIT-RECEIVE TUBE (TR). A gas-filled RF switch that is used as a duplexer.
TRANSMITTER. Equipment that generates and amplifies an RF carrier, modulates the RF carrier with intelligence, and radiates the signal into space.
TRANSMITTER DISTRIBUTOR.A device that reads Baudot code from paper tape and allows a message to be printed on a page printer.
TRANSMITTER END. See INPUT END.
TRANSMITTER FREQUENCY (CARRIER FREQUENCY). The frequency of the unmodulated output of a transmitter.
TRANSMITTER TRANSFER SWITCHBOARD. Equipment that selectively transfers remote station functions and signals to transmitters.
TRANSMITTING ANTENNA. The device used to send the transmitted signal energy into space.
TRANSPARENT. Those substances, such as glass, that pass almost all of the light waves falling upon them.
TRANSVERSE ELECTRIC MODE. A waveguide mode in which the entire electric field is perpendicular to the wide dimension and the magnetic field is parallel to the length. Also called the TE mode.
TRANSVERSE MAGNETIC MODE. A waveguide mode in which the entire magnetic field is perpendicular to the wide dimension and some portion of the electric field is parallel to the length. Also called the TM mode.
TRANSVERSE WAVE MOTION. The up and down motion of a wave as the wave moves outward.
TRAVERSE (BEARING) SIGNAL. In a monopulse radar system, the combination of individual lobe signals that represents target-offset direction and amplitude from the antenna axis.
TREMENDOUSLY HIGH FREQUENCY. The band of frequencies from 300 gigahertz to 3,000 gigahertz.
