French to English translations [PRO] Science - Physics / Acoustics
French term or phrase:spectre fréquentiel
I came across this term in a document about acoustics and need confirmation about a possible translation that I found: frequency domain. Could a specialist please confirm whether this is the correct translation or not.
I would give the context, but I'm afraid it won't be of much help.
Explanation: I would think that the literal translation would be correct here — it's certainly the term I'm familiar with in very many contexts.
Note that, although 'frequency domain' does indeed exist, it is not the same thing at all, and would normally translate a different term; so I wouldn't use it here, unless there is something very specific in your context that would require it.
Sure, Tony. Still, there is a "frequency representation", and also a frequency spectrum", distinct from the representation. The frequency spectrum is within the frequency space, or frequency representation.
Some examples of representations are the discrete variable representation (DVR), plane wave representation, finite basis representation, etc.. each one having advantages and disadvantages depending on the problem to be solved. One normally make the choice that is the most accurate, and if possible the fastest...
Representation would be wrong. Representation refers more or less to the basis set used in forming operator matrices in quantum mechanics. So, an operator has a large number of representations, because one could choose a number of different basis sets to cast it in. This idea of writing the operator as a matrix is called representation. Just like the words we use are representations of our thoughts...
Of course, "frequencydomain" exists, but it refers to the "space" in which the spectrum is presented. Just like a book and a book case not being the same. Also, frequency domain is sometimes referred to as "reciprocal space", especially in solid state physics and crystallography. They are very much one and the same. It's just that differnt disciplines have different preferences.
I think it is most likely frequency representation. The specific context relates to the information picked up by the microphones of a hearing prosthetic and how the signals are processed.
bear in mind that in this domain, a lot of the terminology may have originally come from EN; hence, the literal translation is often a good starting-place for your further research ;-)
"frequency representation" is correct. In other words, the response (the y-axis) is "represented" in the frequency domain (the x-axis), although the initial measurements (as a time series) would have been made in the time domain, eg volts vs. time.
By the way, I'm not sure what you mean by "time-frequency representation"...
Thank you both for correcting what would have been an error on my part.
Should I do likewise with "représentation fréquentielle" and assume that it is the "frequency representation" (as in time-frequency representation), or it is possibly "frequency distribution"?

frequency spectrum
Explanation: The spectrum is not the same as the domain. A frequency spectrum is defined over the frequency domain (in e/m radiation this is generally the reciprocal domain, ie time). Essentially the spectrum gives you the frequency response of the transducer/room/absorber panel etc. Plenty of hits for "frequency spectrum".

Sorry, the reciprocal domain for light etc. is wavelength, not time!
