That is excellent. It is also the missing piece in Monty's presentation.
Whenever he gets to that part, I know I always have the gut feeling "there
are any number of possible waveforms I could draw that satisfy those two
requirements". But the gut feeling is wrong, and the correct answer ("one")
is deeply significant. Thanks for making this so clear.
