Witryna27 kwi 2011 · 6. If you average 5 drifting clocks, the only thing you get is another drifting clock that's harder to correct. It won't be more precise. NTP uses multiple servers to increase precision because it takes network latency into account. Since all your systems are on a fast local network, you just need one server. Witrynathe exaggerated effect of both random phase noise and phase modulation of the clock in the presence of higher input frequencies. The clock input of the ADC should be regarded as the local oscillator port of the ADC, not a digital control sig-nal.
