Noise (electronics) — Electronic noise [1] is a random fluctuation in an electrical signal, a characteristic of all electronic circuits. Noise generated by electronic devices varies greatly, as it can be produced by several different effects. Thermal noise is… … Wikipedia
Operational amplifier — A Signetics μa741 operational amplifier, one of the most successful op amps. An operational amplifier ( op amp ) is a DC coupled high gain electronic voltage amplifier with a differential input and, usually, a single ended output.[1] An op amp… … Wikipedia
Operational amplifier applications — This article illustrates some typical applications of operational amplifiers. A simplified schematic notation is used, and the reader is reminded that many details such as device selection and power supply connections are not shown. Contents 1… … Wikipedia
Image noise — Noise clearly visible in an image from a digital camera Image noise is random (not present in the object imaged) variation of brightness or color information in images, and is usually an aspect of electronic noise. It can be produced by the… … Wikipedia
Logarithmic video amplifier — A logarithmic video amplifier or LVA is typically part of radar and electronic countermeasures microwave systems and sonar navigation systems, used to convert a very large dynamic range input power to an output voltage that increases… … 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
Valve amplifier — A valve amplifier or tube amplifier is a type of electronic amplifier that make use of vacuum tubes instead of solid state semiconductor devices (such as transistors). As any other electronic amplifier they serve to increase the power and/or… … Wikipedia
Microchannel plate detector — from the Daresbury Recoil Separator A micro channel plate (MCP) is a planar component used for detection of particles (electrons or ions) and impinging radiation (ultraviolet radiation and X rays). It is closely related to an electron multiplier … Wikipedia
Bat detector — The term bat detector is usually used to describe a device used to detect the presence of bats by converting their echolocation ultrasound signals to audible frequencies as they are emitted by the bats. There are other types of detector which… … 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
