31Control theory — For control theory in psychology and sociology, see control theory (sociology) and Perceptual Control Theory. The concept of the feedback loop to control the dynamic behavior of the system: this is negative feedback, because the sensed value is… …
32Frequency modulation — See also: Amplitude modulation In telecommunications, frequency modulation (FM) conveys information over a carrier wave by varying its frequency (contrast this with amplitude modulation, in which the amplitude of the carrier is varied while its… …
33Thermistor — A thermistor is a type of resistor with resistance varying according to its temperature. The word is a portmanteau of thermal and resistor . Samuel Ruben invented the thermistor in 1930, and was awarded… …
34Analog-to-digital converter — An analog to digital converter (abbreviated ADC, A/D or A to D) is an electronic integrated circuit, which converts continuous signals to discrete digital numbers. The reverse operation is performed by a digital to analog converter… …
35Spintronics — (a neologism meaning spin transport electronics [1][2]), also known as magnetoelectronics, is an emerging technology that exploits both the intrinsic spin of the electron and its associated magnetic moment, in addition to its fundamental… …
36Monochromator — in a x ray beamline at the Advanced Photon Source, Argonne National Laboratory. A monochromator is an optical device that transmits a mechanically selectable narrow band of wavelengths of light or other radiation chosen from a wider range of… …
37Backscatter — For other uses, see Backscatter (disambiguation). In physics, backscatter (or backscattering) is the reflection of waves, particles, or signals back to the direction they came from. It is a diffuse reflection due to scattering, as opposed to… …
38Voice activity detection — (also known as speech activity detection or, more simply, speech detection) is an algorithm used in speech processing wherein the presence or absence of human speech is detected in regions of audio. The main uses of VAD are in speech coding and… …
