I thought of an interesting analogy to this problem. It’s much less clunky than the “measuring tape” analogy I offered earlier.

Why didn't you answer my question about the 60 Hz in your outlet Slamclick? Frequency is a function of time. But purely in a sense of the period of the wave.

Are you familiar with the term "grasping at straws" Slamclick?

TIME is found by comparing the frequencies.
Or is it the distance that is found by comparing the frequencies.....
What are we measuring here? Time or distance. I say distance.
<i>A radalt does not rely on phase differences. In fact, it is completely oblivious to any phase difference.

But it does matter since (paraphrasing Airplay) the signal is timed by the change in frequency modulation
I never used the term "timed". The frequency of the demodulated received signal is compared to the reference frequency. There is no "timing" done.
