Abstract

In this paper a new asynchronously sampled multi-harmonic signal estimation algorithm is proposed. A phase sensitive frequency estimation algorithm is enhanced for harmonically distorted signals. The performance of the algorithm is demonstrated on numerically generated data and on real harmonically distorted sampled signals. The algorithm is stable and accurate as long as the fundamental component amplitude is larger than any amplitude of harmonic components. Noise is a dominant factor in limiting algorithm accuracy.
