Measurement of Phase Difference Using DSP Algorithms by Non-Coherent Sampling

Michal Krumpholc, Milos Sedlacek
  • Abstract:
    The paper compares nine methods of measurement of the phase difference of digitized sinusoidal noised signals according to their sensitivity to sampling non-integer number of signal periods. The investigated methods can be classified into four groups - modifications of classical zerocrossing based measurements, DFT-based measurements, virtual vector voltmeter and modifications of sine-wave fit algorithm. Results of both simulations and measurements are presented.
