attenuer

Atténuer is a French verb meaning to reduce, lessen, or weaken the intensity, strength, or impact of something. It is used in a wide range of contexts, from physical phenomena to abstract effects. The infinitive is attenuer, with conjugations such as atténue, atténues, atténue, atténuons, atténuez, atténuent. The term comes from Latin attenuare through Old French, and it is cognate with the English attenuate.

In scientific and everyday usage, attenuating describes the process of diminishing a quantity as it propagates

An attenuator is a device or component that implements attenuation. In electronics, a fixed attenuator provides

Attenuation is commonly quantified in decibels (dB). For power, attenuation in dB is 10 log10(Pout/Pin); for voltage
