1. Attenuator
   [genetics] Attenuation is a regulatory feature found throughout Archaea and Bacteria causing premature termination of transcription. Attenuators are 5`-cis acting regulatory regions which fold into one of two alternative RNA structures which determine the success of transcription. The foldin...

2. Attenuator
   [electronics] An attenuator is an electronic device that reduces the amplitude or 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 attenuato...

16. attenuator
    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, ...

17. Attenuator
    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.
