在具有周期输入和稳态周期响应的非线性电路的机助分析中,Trick提出了著名的快速算法,其简单迭代法的迭代公式是 x_0~((f+1))=integral from n=0 to (f+1)T f(x,t)dt+x_0~((0)) (1)本文认为在进入稳态之前,式中的f(x,t)不是周期函数,并指出文献[2]中的两处疏忽。 一、问题的提出 文献[2]为了确立式(1),给出了如下证明: In the machine-based analysis of nonlinear circuits with periodic inputs and steady-state periodic responses, Trick proposed the well-known fast algorithm whose iterative formula for simple iteration is x_0 ~ ((f + 1)) = integral from n = 0 (1) This paper considers that f (x, t) is not a periodic function before entering the steady state, and it is pointed out in [ 2] in two negligence. First, the issue of the proposed literature [2] In order to establish equation (1), gives the following proof:
