| Abstract: | Phase - sensitive detector is an important part of RLC DigiBridge. The efficiency and performance of phase - sensitive detector determine the measurement precision of whole instru- ments. The phased effect is directly connected with phased method. In this paper, digital full - wave phase detecting is applied to improve efficiency and effect of phase - sensitive detector. By means of it, measurement precision of RLC digibridge is enhanced. |
