I'll give you another example to chew on, take two different

There is no delay involved in that example.

There is no "phase" in this example. Perhaps a standard
text would be the better place to start, rather than newsgroup
postings, which (particularly true in this issue) can be
marginal.

There is phase in that example. That you cannot understand that
is your loss.

Good fortune,
