ABSTRACT:
A first oscillator is associated with a pressure detector so that frequency of an output signal of the first oscillator varies in response to variations of the detected pressure. A second oscillator having a same construction as the first oscillator is provided for determining a sampling period of the output signal of the first oscillator, thereby compensating for variations of the frequency of the output signal derived from the first oscillator due to variations of temperature, humidity, a power supply voltage, etc.
