| 摘 要： | 本文在离散小波变换矩阵表示的基础上,由时域方程直接推导了电阻、电感、电容、变压器等电路元件在小波域的等效电路方程,并将之应用于电路分析中.该方法具有推导简单,且能分析电路时-频特征的特点,较单独的时域或频域分析更适合于暂态和瞬变信号的分析.

| Abstract: | Based on the matrix expression of the discrete wavelet transform, the equivalent circuit equations of the circuit components such as resistor, inductor, capacitor and transformer are built in the wavelet domain directly deduced from the time domain equations in this paper. This method is also applied in the circuit analysis. It has the advantage of simple deduction and can be used in the analysis of the time-frequency characteristic of the circuit. It is more suitable to the transient signal analysis than the method based on time domain or frequency domain only. |
