#139595 - What about phase noise? Responding to: ???'s previous message |
Mehmet said:
If we use 1 ppm clock our error will be 1 ns, and light travels 30 cm in 1 ns. This is our optical error. Mehmet, this 1ppm is a statical specification, means if you take the average over a huge number of periods. What you probably forget is the phase noise or jitter. Have you considered that? Kai |
