| Résumé | The advantage of the new sampling approach to overcome transient effect in staircase waveform is described. Based on this sampling approach, a general form is developed in this paper. In this form, more samples are used for calculations in the measurement. It provides a better basis to achieve a lower uncertainty as reduced noise impact and more information. A sine-wave experiment shows the advantage of the multi-point approach. When the more frequency components of the measured signal are asked, it faces a matter of unequal-interval sampling. It is found that the aliasing effect of sampling is solvable under the discussed condition. A novel method is developed to perform Fourier transform to extend application of Nyquist Theorem, in which the matrixes to solve the relative equation set are given out in the forms of digital and formula. Experiments for a non-sinusoidal wave validates that the higher frequency components can be analyzed, in which a differential sampling scheme is proposed. |
