Description

A simple method is presented to measure very small phase differences in the range of microradians between two ac voltages. The voltages are combined linearly and one of them is adjusted in amplitude such that the output is a minimum. This minimum voltage is proportional to the phase shift to be measured. The method is applicable from power to radio frequencies
