摘要
对计算机辅助测试数据处理中的数字信号转换为模拟信号的复原技术进行了研究。简述了信号复原的基本理论，分析了常用方法的原理与不足，给出了用样条函数逼近作为信号复原方法在实际应用中的优点。
Research on signal recovery about digital signal to analog signal in computer aided testdata processing is presented in this paper. Basic signal recovery theory is discussed,and tradi-tional methods and their defects are analvzed.As a result,a new signal recovery technologyby using spline function approximation and its advantage in application are given out。
