distortion to the overall rms signal, in
dB or percent.
THD+N Signal-to-THD Plus Noise: The ratio in
decibels of the overall rms signal to the
rms signal of harmonic distortion plus
noise introduced.
Thermistor A semiconductor sensor that exhibits a
repeatable change in electrical
resistance as a function of
temperature. Most thermistors exhibit a
negative temperature coefficient.
Thermocouple A temperature sensor created by joining
two dissimilar metals. The junction
produces a small voltage as a function
of the temperature.
Throughput Rate The data, measured in bytes/s, for a
given continuous operation.
Transducer A device that responds to a physical
stimulus (heat, light, sound, pressure,
motion, flow, and so on), and
produces a corresponding electrical
signal.
Transfer Rate The rate, measured in bytes/s, at which
data is moved from source to
destination after software initialization
and set up operations; the maximum
rate at which the hardware can
operate.
U
Unipolar A signal range that is always positive
(for example, 0 to +10 V).
Z
Zero-Overhead Looping The ability of a high-performance
processor to repeat instructions without
requiring time to branch to the
beginning of the instructions.
