# The paired domains of integral transforms. Is there a moniker?

Use the Fourier transform example. For several years I thought of Fourier transform pairs as functions in two domains which were paired by a term "conjugate domains" and significantly the dimensions of one are the reciprocal of the dimensions of the other. I'm not now able to find my reference on this. What moniker would be proper to describe the relationship of the two domains?

• @Creator "moniker" typically means "name/term"... but still I find this question vague – peek-a-boo May 23 at 0:05
• OK so let me state a sentence given that the question is vague. Either it is incorrect terminology/usage or not: "The conjugate domain of the time domain is the frequency domain." – Thomas A. Groover May 23 at 2:02
