本文提出了冲激激励信号采用频域离散化,然后求取冲激响应数值的方法。因为冲激激励信号在每一个频域离散点可以应甩正弦稳态分析。所以避免建立动态网络方程,确定迭代步长和初值等一系列问题。使计算大大简化。此外,在整个计算过程中还可以同时获得网络的频率特性。 In this paper, we propose a method to discretize the excitation signal in the frequency domain and then obtain the impulse response value. Because the impulse excitation signal in each frequency domain discrete points can be thrown sinusoidal steady-state analysis. So to avoid the establishment of dynamic network equations to determine the iteration step and the initial value of a series of problems. Make the calculation greatly simplified. In addition, the frequency characteristics of the network can be obtained simultaneously throughout the calculation.
