TUBE STATIC CONDITIONRefers to the testing condition in which a tube has certain voltages applied but is not in its normal operating condition [16]. |
TUNED CIRCUIT(1) A circuit consisting of inductance and capacitance that can be adjusted for resonance at a desired frequency [9]. (2) A circuit that is used as a filter which passes or rejects specific frequecies [16]. (3) An LC circuit used as a frequency-determining device [8]. |
TUNED LINEAnother name for the resonant line. This line uses tuning devices to eliminate the reactance and transfer maximum power from the source to the line [10]. |
TUNNEL DIODEA heavily doped semiconductor device that has high gain and fast switching capabilities [7]. See NEGATIVE-RESISTANCE ELEMENT [11]. |
TUNNELINGThe piercing of a potential barrier in a semiconductor by a particle (current carrier) that does not have sufficient energy to go over the barrier [11]. |
TURNOne complete loop of a conductor about a core [2]. |
TURNS RATIOThe ratio of the number of turns in the primary winding to the number of turns in the secondary winding of a transformer [2]. |
TURNSTILE ANTENNAA type of antenna used in vhf communications that is omnidirectional and consists of two horizontal half-wave antennas mounted at right angles to each other in the horizontal plane [10]. |
TWISTED PAIRA line consisting of two insulated wires twisted together to form a flexible line without the use of spacers [10]. |
TWO-DIMENSIONAL RADAR(2D)—Measures the range and bearing to a target [18]. |
