摘要 基于PWM信号的纵轴及半波对称特性,对PWM信号的傅里叶级数表达式进行了详细分析,并用Matlab进行了仿真,指出了现有一些PWM信号的傅里叶级数表达式中存在的错误,为PWM信号的频谱分析提供了依据。 Based on the symmetry property of the PWM signal with the longitudinal axis and half wave,the paper analyzes its fourier series expression in detail.Futhermore,MATLAB software has been used to simulate.Errors in the fourier series expression of PWM signal have been spotted.Meanwhile the basis of spectrum analysis on PWM signal has been provided as well.
