Proposed method of realization of RLCG meter

Abstract

The RLCG meter is usually constructed from separate analogue oscillator as a source of test signal and two phase detectors that obtain real and imaginary part. In some cases the real and imaginary parts are calculated by using DFT (Discrete Fourier Transform). More sophisticate solution is described in this paper. Proposed solution is based on fully digital conception, when test signal is generated in digital form and this signal (in the same form) is simply used for phase detection.
