Dämpfungssatz

English translation: Damping factor / rate

German to English translations [PRO]
Science - Mathematics & Statistics / Laplace transformation
German term or phrase: Dämpfungssatz
In the context of "Ähnlichkeitssatz" (similarity theorem) and "Verschiebungssatz" (shift theorem)

I think it may be "frequency shift(ing) theorem, but I can find any confirmation.

Thanks for any help.

English translation:Damping factor / rate
Explanation:
This is an exp(-at) factor in the Laplace Transform which generally is a frequency shift but which gives exponential decay when Re(a) > 0.

Thanks, everyone, for your help.
I finally went with "modulation theorem" based on Kim's and Johanna's references plus:
http://www.formel-sammlung.de/ld-Laplace-Transformation-1182.html
(German)
and
http://instruct.uwo.ca/engin-sc/ece233b/notes/ECE233b-Laplace_ch12.pdf
(English, on p. 13)

Further research shows that "damping factor" is 100% correct, also in connection with Laplace transformations and transforms, but in a slightly different context from the one I'm dealing with. I'm sorry I couldn't provide more detailed context, but I couldn't find a way to copy the relevant formula into the question box.
