Hi Gardner in "Phaselock Techniques" has figure 4.8 that is a pretty good starting point.

When the reference is gone, the PLL will "flywheel" according to whatever the loop filter does. (we can turn off the "input" to the filter, so we're not trying to track noise).. What I'm particularly interested in is the behavior in the PLL when the reference returns. The overall situation is where we are trying to make a frequency/phase measurement over 10-100 seconds, where the reference has a 50% duty cycle, and is on for a second, off for a second. I can fairly simply model this, or just try it, but I'm looking for some references to an analytical approach. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
