attenuation rate; attenuation factor
Technical term used in physics, engineering, and signal processing for the rate or factor by which a signal, wave, or physical quantity diminishes.
Please calculate the attenuation rate of this circuit.
The larger the attenuation factor, the faster the signal weakens.
Compound of 減衰 (attenuation) and 率 (rate, factor). The exact historical derivation is uncertain, but the word follows standard technical compounding patterns.
