Now, this is a homodyne


She knew the words she wanted to say-about seeing Morse or at least her mind knew. Yet she was aware that those words had homodyned little, if at all, with the words she’d actually used.
—Colin Dexter. The daughters of Cain. London: Pan, 1994, p.362.

“Homodyned?” … to the dictionary:

Homodyne, adj. of or pertaining to reception by a device that generates a varying voltage of the same or nearly the same frequency as the incoming carrier wave and combines it with the incoming signal for detection.

Hmm … a bit pretentious, Mr Dexter. By the way, do you remember the primitive radios we used to try to make when we were boys? This circuit is a homodyne.
