  • Digital phase measuring system and method
    Patent number: 6049297
    Abstract: A digital phase measuring system and method for measuring the phase difference between two signals including generating quadrature clock signals for a first reference signal, converting a second measured signal from analog to digital form by sampling the second measured signal using the quadrature clock signals to produce quadrature cartesian samples of the measured signal, and converting the quadrature cartesian samples to polar coordinates to define the polar phase coordinate representative of the phase difference between the two signals.
