  • Interference rejection through circle fitting
    Patent number: 7822579
    Abstract: A method and apparatus for measuring electrical signals measures an electromagnetic wave having an interference component at a center frequency and at multiple times to obtain data points. The positions of the data points on a complex plane are calculated. Chords of a circle on the complex plane, wherein the chords passing between pairs of the data points, and the circle fit to the data points are calculated. The chords are used to determine an approximate center of the circle wherein the position of the approximate center of the circle on the complex plane represents the electromagnetic wave with the interference component removed. An indication of the measured electromagnetic wave having the interference component removed is output from the apparatus.
