Acceleration or sudden force impact events cause fluctuations in the resonant frequency of quartz crystal and surface acoustic wave oscillators, increasing jitter and phase noise. There exists a mathematical relationship which relates these fluctuations in the natural frequency to the magnitude and direction of the accelerating source. This acceleration sensitivity can therefore be utilized to track changes in the oscillator resonant frequency referred to as jitter or phase noise to determine the magnitude of acceleration over time. | 2020-04-16 |
