Attenuator could mean: * Attenuator (electronics), an electronic device that reduces the amplitude of an electronic signal. * Optical attenuator Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultravi ..., an electronic device that reduces the amplitude of an optical signal. * Attenuator (genetics), a specific regulatory sequence transcribed into RNA. * Impact attenuator, used on highways as a crumple zone in case of a car crash.

Attenuator (electronics)
An attenuator is a Passivity (engineering), passive wideband, broadband Electronics, electronic device that reduces the Electric power, power of a signal without appreciably distortion, distorting its waveform. An attenuator is effectively the opposite of an amplifier, though the two work by different methods. While an amplifier provides gain (electronics), gain, an attenuator provides loss, or gain less than unity. An attenuator is often referred to as a "pad" in audio electronics. Construction and usage Attenuators are usually Passivity (engineering), passive devices made from simple voltage divider networks. Switching between different resistances forms adjustable stepped attenuators and continuously adjustable ones using potentiometers. For higher frequencies precisely matched low Standing wave ratio, voltage standing wave ratio (VSWR) Electrical resistance, resistance networks are used. Fixed attenuators in circuits are used to lower voltage, Dissipation, dissipate power, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
