对应不同的a值产生一组矢量来表示高斯脉冲波形，并计算其相应的ESD。最后，画出了各个a值所对应的脉冲波形及其ESD-a different corresponding values of a group vector to express Gaussian pulse waveform, and calculated the corresponding ESD. Finally, paint all of a value corresponding to the pulse waveform a

产生高斯脉冲的前15阶导函数。该函数的输入参数为：矢量t定义时间轴；高斯脉冲导函数的阶数k，取值范围[1，15]-have a Gaussian pulse of 15 derivative function. The function of the input parameters : vector defined time frame t; Gaussian pulse derivative function of order k, value in the range [1,15]

估算并画出高斯脉冲的前15阶导函数的-10dB带宽。函数以下列变量为输入：a的最小值alphamin，-estimates and the mapping out of the Gaussian pulse before 15 derivative function-10dB bandwidth. Function for the importation of the following variables : a minimum of alphamin.
