THIN FILM COMPONENTSPassive 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 ARRAYAn array with two parasitic elements (reflector and director) and a driven element [10]. | |
THROWIn a switch, the number of different circuits each pole can control; for example, single throw and double throw [3]. | |
THYRATRONA gas tube used as a modulator switching device [18]. | |
THYRATRON TUBEA 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 COILA 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 CONSTANTTime 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 LAGThe delay in a servosystem between the application of the input signal and the actual movement of the load [15]. | |
TIME-DIVISION MULTIPLEXINGThe 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]. | |
