There are several references to it, but no quotes.
What I'm particularly looking for is the original justification for the claim that sampling is the mathematical equivalent of multiplying by a comb of Dirac's Delta Function and its delayed siblings.
This claim does not appear in Oppenheim & Schafer which is referenced as the "bible" for DSP, and yet appears in all modern texts.
The claim is at odds with everything that electrical engineers are taught about Delta Functions up to that point.
