A terminology question I suppose about the derivation of the term
"Superheterodyne" more than anything else:
Does the "Super" actually mean anything?
My recollection is that Armstrong used the term "supersonic heterodyne"
to note the fact that the beat frequency between the signal and LO
was "supersonic."
Ultrasonic of course, so it's been the wrong name all along.
