COBISS.SI-ID: 11575892In paper, algorithms for fast measurement and estimation of the three basic sine-wave parameters in the measurement time below one period are presented. When the time is shortened below the signal period, the DC coefficients of the discrete Fourier transformation are taken into account using two Rife-Vincent windows class I with different orders. First, frequency is estimated by the quotient of the DC coefficients, and then the amplitude and the phase are estimated by the 3-parametric sine-fit algorithm. Simulations changing offset, harmonics and noise in the signal support the analysis.
