Abnahme der Amplitude einer Schwingung (zeitl. D.) oder Welle (räuml. D.), die durch Energieverlust verursacht ist. Als D.verhältnis wird der Quotient von zwei aufeinanderfolgenden Amplituden bezeichnet.
Abschwächung eines Schwingungsvorgangs durch dauernden Energieverlust; bei mechan. Schwingungen z.B. durch Reibung, bei elektr. Schwingungen durch Verluste in der Isolation.
ETYM Latin attenuatio: cf. French atténuation.
1. The property of something that has been weakened or reduced in thickness or density.
2. Weakening in force or intensity; SYN. fading.
Power loss in an electrical system. In cables, generally expressed in dB per unit length.
The reduction of response at the resonant frequency through the use of a damping media such as oil. Usually specified as the ratio of critical damping.
A decrease in the amplitude of a signal over time.
1. A gradual decrease; as of stored charge or current; SYN. decline.
2. An inferior state resulting from the process of decaying.
3. The organic phenomenon of rotting; SYN. decomposition.
4. The phenomenon of spontaneous changes in the nucleus of an atom; SYN. radioactive decay.
5. The process of gradually becoming inferior.
6. The spontaneous disintegration of a radioactive substance along with the emission of ionizing radiation; SYN. radioactive decay, disintegration.
