摘要
A characteristic automatic compensating apparatus of an oscillator includes oscillating means, temperature detecting means, characteristic determining means for measuring a drift value of an oscillating frequency while changing the temperature and for determining a coefficient of an approximated equation representing temperature and the drift value, storing means for storing the coefficient, drift value predicting means, and characteristic updating means for updating the coefficient by the measured drift value of the oscillating frequency and the temperature, wherein the characteristic determining means represents the approximated equation representing the characteristic of the temperature detected by the temperature detecting means and the drift value of the oscillating frequency of the oscillating means by a polynomial.
