摘要
The dependence of a tuning-fork quartz crystal oscillator's frequency f on temperature T is observed over the temperature range -5 to 20 degrees C. From this, a parabolic f(T) function is fit to the crystal's data, and used to compensate for sampling period drift in an Analog to Digital Converter (ADC) system based around this crystal at various temperatures. Resolution and uncertainty of this method are discussed.
