The Evaluation Methods of Characteristics of Triangle Waveforms using Least Square Methods

In this paper, A method about the evaluation of triangle waveform characteristics is introduced. By using the waveform measurements and the least square method, the top, the base, the middle value, the amplitude, the frequency of triangle waveform, and the slope of edge, the edge linearity of waveforms are evaluated precisely. The evaluation courses and some technical problems are discussed in detailed, the error analysis is presented. Some test results have proved the effectiveness and practicability of the method. It could be applied to the characteristics and performance evaluation of triangle waveform generators.
