| 摘 要： | 研究提出了一种通过测量等效采样示波器幅度响应来获得其相位响应的算法.此方法是基于Kramers-Kronig关系式并配以基于NTN校准的相位响应测量实现的.实例证明:虽然Kramers-Kronig变换计算时的截断造成了相位估计上非常大的误差,但是此误差可以通过少量的正交基函数拟合出来.作为一个实例,本文利用NTN校准...

| Abstract: | Describes an algorithm for determining the minimum phase response of equivalent sampling oscilloscopes.The procedure is based on Kramers-Kronig relation in combination with the harmonic phase response measurement of NTN calibration.Although the truncation of Kramers-Kronig transform gives rise to large errors in estimated phase,these errors can be fitted using three basis functions.As an example,we got the phase response reconstruction of sampling oscilloscope in frequency domain;its frequency resolution ac... |
