THIN FILM COMPONENTS

Passive circuit elements (resistors and capacitors) deposited on a substrate
to a thickness of 0.0001 centimeter [14].

THREE-DIMENSIONAL RADAR

(3D)—A radar set that measures the range, bearing and altitudes of a target [18].

THREE-ELEMENT ARRAY

An array with two parasitic elements (reflector and director) and a driven
element [10].

THROW

In a switch, the number of different circuits each pole can control; for example, single throw and double throw [3].

THYRATRON

A gas tube used as a modulator switching device [18].

THYRATRON TUBE

A gas-filled triode in which a sufficiently large positive pulse applied to the
control grid ionizes the gas and causes the tube to conduct, after which the control grid has no effect in conduction [6] [12].

TICKLER COIL

A small coil connected in series with the collector or plate circuit of a transistor or tube and inductively coupled to the base or grid-circuit coil to establish feedback (regeneration) [9].

TIME CONSTANT

Time required for an exponential quantity to change by an amount equal to 63.2 percent of the total change that can occur [2] [9].

TIME LAG

The delay in a servosystem between the application of the input signal and the actual movement of the load [15].

TIME-DIVISION MULTIPLEXING

The process that periodically samples the full 360 degrees of each sine wave. The sample can be of a received signal or of a signal to be transmitted [17].
