[electronics] Not to be confused with Squelch An attenuator is an electronic device that reduces the power of a signal without appreciably distorting its waveform. An attenuator is effectively the opposite of an amplifier, though the two work by different methods. While an amplifier provides gain, an attenuator provides loss, or gain less t...

used in e.s.r, the attenuation of the microwave power passing along a waveguide is achieved by means of a metal plate placed along the axis of the waveguide. The degree of attenuation increases as the plate is moved away from the wall of the waveguide toward the center. In IR and UV spectroscopy, the attenuator is a toothed comb, grid, ...

A device which reduces the amount of energy reaching a sensor. Attenuators are typically used when the radiant energy would saturate a detector. The QNDS,QNDS2 and QNDS3 filters are attenuators that reduce flux density at the detector by factors of 10, 100 and 1000, respectively.

An attenuator is an electronic testing instrument that decreases the magnitude or power of a signal. Due to its composition, this device can effectively diminish the amplitude of the signal without compromising signal purity or causing noticeable distortion. Whereas an amplifier increases the magnitude or frequency of optical or acoustic waves, an ...
