周期高斯一介导、高斯二介导即高斯脉冲（即UWB信号）的功率谱图像，对应不同的占空比和不同的脉冲形式，随着阶数的增加中心频率右移，频谱也为高斯形式，且随着周期数增多，呈现线谱形式。
English Description：
The power spectrum images of periodic Gaussian one mediated and Gaussian two mediated, i.e. Gaussian pulse (i.e. UWB signal), correspond to different duty cycles and different pulse forms. With the increase of the order, the center frequency shifts to the right, and the spectrum is also in Gaussian form, and with the increase of the number of cycles, it presents the line spectrum form.
