What does "Allan Deviation" mean?
Table of Contents
Allan Deviation is a way to measure how stable a frequency source is over time. It helps us understand how much the frequency of a signal changes as we look at it over different periods.
Importance
By studying Allan Deviation, scientists can tell if a frequency reference, like a laser or an oscillator, stays steady or fluctuates. This is crucial for devices that rely on precise timing and frequency, such as clocks or sensors.
Applications
Many technologies, from GPS systems to communication devices, need reliable frequency references. By analyzing Allan Deviation, researchers can improve the performance of these systems, ensuring they work accurately and efficiently.
