  • Abstract
    This paper describes a method to determine the phase angle between two voltages via complex ratio of frequency-shifted sinusoidal signals. This allows the use of precision-sampling methods for signals with frequencies up to the audio-frequency range and with rms voltage levels up to 7 V and a maximum voltage ratio of 1:10
