摘要：
A programmed phase meter for the detection of small phase deviations is described. The device is designed for a remote vibration meter. The application of digital signal processing ensures the detection of differential or simple phase deviations at a specified carrier frequency of 10.7 MHz with a sensitivity of approximate to 10(-5)pi rad.
