测试信号的反失真研究

Research on Counter Distortion of Testing Signal

不失真测试是测试技术最基本的理论和技术问题。不失真测试的条件限定了工程中常用传感器的应用范围。从理论上分析研究了常用一阶、二阶测试系统进行测试的信号反失真问题，不仅扩展了传感器的应用范围，而且丰富了信号处理理论。

The test of no distortion is the most basic problem of theory and technology of measurement technology. The applying scope of sensor, which is in common use for engineering, is limited by the test of no distortion. In this paper, the problem of no distortion of the first order and second order testing system is analyzed and researched from theory. This not only extends the applying scope of sensor, but also enriches the theory for processing signal.
