Hi everyone,
I have a problem in understanding the difference between hold range and pull out range. It seems that this two are just the same. Can anybody help me to explain this?
From Roland E. Best:
The hold range: This is the frequency range in which a PLL can statically maintain phase tracking. A PLL is conditionally stable only within this range.
The pull-out range: This is the dynamic limit for stable operation of a PLL. If tracking is lost within this range, a PLL normally will lock again but this process can be slow if it is a pull-in process.
