ANALYSIS OF A NON-ITERATIVE ALGORITHM FOR THE AMPLITUDE AND PHASE DIFFERENCE ESTIMATION OF TWO ACQUIRED SINEWAVES

Fernando M. Janeiro, Pedro M. Ramos, Mouhaydine Tlemcani, A. Cruz Serra
  • Abstract:
    In this paper, a non-iterative algorithm for amplitude and phase difference estimation of two acquired sinewaves is presented and analyzed. The method is based on the least-squares fitting of ellipses where the common signal frequency is eliminated from the algorithm. requires the strict definition of the convergence criteria to stop the iterative method.
