Frequency counter |
摘要 |
A frequency counter employs a temperature sensitive oscillator mounted in proximity to a master crystal oscillator to provide an output frequency which varies appreciably with changes in ambient temperature and the frequency of the temperature sensitive oscillator is periodically counted and compared to a table of correction factors stored in memory to select a correction factor which is applied to the counted frequency of an input signal to provide a temperature corrected frequency count.
