Technically, what is the difference between "time alignment" and "phase coherence"?What observable property diagnoses either one of these? Say with test signals & a A/D converter & computer, how would you know one vs another?
What is the simplest canonical physical representation of each or the absence of them?
I've never really understood this at technical level.
