Yes, most of the papers in this area are quite theoretic. So far i've
not found anything applicable to time-nuts kind of use. Those papers
that deal with real world injection locking are mostly for integrated
circuits (90° phase shifter, frequency doubler or divider) and thus
are quite specific to the environments there.
I have not gone trough the math in detail and calculated what would
would come out in a injection locked quartz crystal. Maybe i should sit
down and do the math...
I pity people who can't find laughter or at least some bit of amusement in
the little doings of the day. I believe I could find something ridiculous
even in the saddest moment, if necessary. It has nothing to do with being
superficial. It's a matter of joy in life.
