摘　　要：本文利用有限状态序列机概念代替传统的多项式近似法,计算出线路码经过非线性电路处理后的信号功率谱密度。计算结果以精确的闭合公式给出,且与实测曲线相吻合。A noval method employing a finite-state sequential machine is presented to evaluate precisely the power spectra density of signal, instead of conventional method adopting approximate second order poly-momial method. An expression of the closed form of the power spectra density is successfully obtained and the result is in good agreement with the measured curve.
