Phase-locked loop — PLL redirects here. For other uses, see PLL (disambiguation). A phase locked loop or phase lock loop (PLL) is a control system that generates an output signal whose phase is related to the phase of an input reference signal. It is an electronic… … Wikipedia
Phase detector — A phase detector is a frequency mixer or analog multiplier circuit that generates a voltage signal which represents the difference in phase between two signal inputs. It is an essential element of the phase locked loop (PLL).Detecting phase… … Wikipedia

Product detector — A product detector is a type of demodulator used for AM and SSB signals. Rather than converting the envelope of the signal into the decoded waveform like an envelope detector, the product detector takes the product of the modulated signal and a… … Wikipedia
Envelope detector — An envelope detector is an electronic circuit that takes a high frequency signal as input, and provides an output which is the envelope of the original signal. The capacitor in the circuit stores up charge on the rising edge, and releases it… … Wikipedia
Metal detector — A U.S. Army soldier uses a metal detector to search for weapons and ammunition in Iraq A metal detector is a device which responds to metal that may not be readily apparent. The simplest form of a metal detector consists of an oscillator… … Wikipedia
Frequency 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… … Wikipedia
Lock-in amplifier — A lock in amplifier (also known as a phase sensitive detector) is a type of amplifier that can extract a signal with a known carrier wave from extremely noisy environment (S/N ratio can be as low as 60 dB or even lessFact|date=December 2007). It… … Wikipedia
Fluorescence lifetime imaging — or FLIM is a powerful tool for producing an image based on the differences in the exponential decay rate of the fluorescence from a fluorescent sample. It can be used as an imaging technique in confocal microscopy, Two photon excitation… … Wikipedia
