Abstract
The features of calculating the group delay time of a signal based on digital measurements of the S parameters of microwave devices are considered. Methods for calculating the group delay time of a signal with a random noise component are studied based on differentiation by the increment method and approximation. A method for calculating the group delay time based on the differentiation method using sliding piecewise linear approximation is proposed. This algorithm is more resistant to the noise component of the signal than standard method of calculating the group delay time of a signal developed using the example of the one-sided difference method and has less computational complexity than the method presented in the article based on quadratic approximation. The results of testing the operation of the described methods are presented, which illustrate that the methods are suitable for calculating the group delay time.
摘要 考虑了根据微波器件 S 参数的数字测量计算信号群延迟时间的特点。研究了基于增量微分法和近似法计算带有随机噪声分量的信号群延迟时间的方法。提出了一种基于微分法、使用滑动片断线性近似的群延迟时间计算方法。与使用单边差分法实例开发的计算信号群延迟时间的标准方法相比，该算法对信号噪声分量的抗干扰能力更强，计算复杂度也低于文章中提出的基于二次逼近的方法。文中介绍了测试所述方法运行的结果，说明这些方法适用于计算群延迟时间。
