摘要
本文给出沿轴线方向测量非线性电路和系统Volterra前三阶核的快速有效方法。这是作者们以前工作(1990)的续篇。引用以前工作的结果,并在输入信号中加入直流项,可以得到非线性系统在轴线上的高阶核H_2(jω,0),H_3(jω,0,0),H_3(jω_1,jω_1,0)等。
The fast and efficient method for measuring high-order Volterra kernels along axis is given. This is a sequel of the authors former papers (1990). Using the conclusions of those papers mentioned above, and combining the DC component with the input signals, the high-order kernels of nonlinear system H2(jw,0),H3(jw,0,0), H3(jw1,jw2,0) can be, measured with many points.
