| Abstract: | Based on analysis of current status of sine waveform distortion measurement, the distortion measurement technique based on curve-fit method is discussed in t his paper. Aiming at the problem that curve-fit equation is difficult to solve, a simplex-based data processing method is proposed. The experimental results demon strate that the method is fast and accurate, and it can curb the bottleneck prob lems in digitized measurement of signal distortion. |
