摘　　要：本文对通信原理教材和本科教学中数字基带信号功率谱分析方法作了简要介绍,指出其存在的不足。提出了基于计算机仿真的数字基带信号功率谱分析教学法,并以CMI码和AMI码为例给出了基于Systemview的功率谱求解方法。实践证明,此方法可以简便有效地完善教学内容。This article introduces the power spectra analysis of the digital baseband signals in the undergraduate texts and teaching of communication principles and points out the disadvantage. It proposes a teaching technique of the analysis of power spectra for digital baseband signals based on Systemview and gives the power spectra of CMI and AMI as examples to explains how to get the power spectra based on Systemview. Practice shows that this meth- od can improve the issue simply and effectively.
