Definition of Attenuator

Babylon English

device that reduces the amplitude of an electronic signal (Electronics)
Attenuator Definition from Science & Technology Dictionaries & Glossaries
Telecommunication Standard Terms
1. In electrical systems, a network that reduces the amplitude of a signal without appreciably distorting its waveform. Note 1: Electrical attenuators are usually passive devices. Note 2: The degree of attenuation may be fixed, continuously adjustable, or incrementally adjustable. Fixed attenuators are often called pads, especially in telephony. Note 3: The input and output impedances of an attenuator are usually matched to the impedances of the signal source and load, respectively. 2. In optical systems, a device that reduces the amplitude of a signal without appreciably distorting its waveform. Note 1: Optical attenuators are usually passive devices. Note 2: The degree of attenuation may be fixed, continuously adjustable, or incrementally adjustable.
Fiber Optics, Optical Networking Terms
1. In electrical systems, a usually passive network for reducing the amplitude of a signal without appreciably distorting the waveform. 2. In optical systems, a passive device for reducing the amplitude of a signal without appreciably distorting the waveform.
AJA_Glossary of Wireless, RF and Microwave Terms
A device or network that absorbs part of a signal and transmits the remainder with a minimum of distortion.
Attenuator Definition from Computer & Internet Dictionaries & Glossaries
Electronic Music Glossary
Attenuate means to reduce in force, value or amount. An Attenuator is a device that reduces the value of something, usually the amplitude of a signal.
Glossary of Electronic Music Terms
A potentiometer (pot) that is used to lower the amplitude of the signal passing through it. The amplitude can usually be set to any value between full (no attenuation) and zero (infinite attenuation). Pots can be either rotary or linear (sliders), and can be either hardware or "virtual sliders" on a computer screen.
