..
turn-off time
Sum of storage time and fall time.
turn-on time
Sum of delay time and rise time.
turns ratio
Ratio of the number of turns in the secondary winding of
a transformer to the number of turns in the primary
winding.
telephone
Device made to convert sound waves into
electrical waves
telephone line
Wires existing between subscribers and stations
in a telephone system.
telex
Teletypewriter exchange service.
temperature coefficient of
frequency Rate at which
frequency changes with temperature.
tera (T)
Metric prefix that represents 1012.
terminal
Point at which electrical connections are made.
tesla (T)
Unit of magnetic flux density. (1 tesla = 1 Wb/m2).
thermal relay
Relay activated by a heating element.
thermometry
Refers to the measuring of temperature.
thermostat
Device that opens or closes a circuit in response to
changes in temperature.
thick-film capacitor
Capacitor consisting of two thick-film layers of
conductive film separated by a deposited thick-layer
dielectric film.
thin film capacitor
Capacitor in which both the electrodes and the
dielectric are deposited in layers on a substrate.
thyristor
A term used to classify all four layer semiconductor
devices.
time division multiplexing
(TDM) Transmission of two or more signals on the same
path, but at different times.
transducer
Device that converts energy from one form to another.
transformer
Inductor with two or more windings.
transistor
Term derived from "transfer resistor." Used as
amplifer-Type-Npn & Pnp Transistors
transmission
Sending of information.
transmitter
Device used to achieve transmission.
trigger
Pulse required to initiate a circuit action.
triggering
A trigger is a type
of system that uses simple schedule to decide which
processes in a particle detector to keep when only a
small fraction of the total can be stored
