本文提出了一种基于Haar小波变换的电路分析方法。最近，人们提出了用Daubechies小波分析电路的方法。然后，得到了用代数方程组求解暂态问题的类傅立叶方法和类拉普拉斯方法，避免了数值时间推进。在这种方法中，表示积分和导数的矩阵不容易处理。在该方法中，我们可以很容易地处理这类矩阵，从而以牺牲更多的基数为代价，使计算和理解变得更容易。
In this paper, we propose a method to analyze circuits using Haar wavelet transform. Recently, the method to analyze the circuit using Daubechies wavelets has been proposed. Then a Fourier-like approach as well as Laplace-like one for the solutions of transient problems by an algebraic system of equations is obtained and numerical time stepping is avoided. In that method, the matrices to express the integral and derivative are not easy to handle. In the proposed method, we can easily treat such matrices, thus the calculation and its comprehension become easier at the expense of more number of bases.
