观察高斯序列的时域和幅频特性。
①固定p=8，q分别等于2、4、8，观察它们的时域和幅频特性，了解当q取不同值时，对信号序列的时域和幅频特性的影响
②固定q=8，p分别等于8、13、14，观察p变化对信号序列时域和幅频特性的影响，注意p等于多少时，会发生明显的泄露现象，混叠是否也随之出现？
记录实验中观察到得现象，绘出相应的时域序列和幅频特性曲线
English Description：
Observe the time domain and amplitude frequency characteristics of Gaussian sequence < p > ① fixed P = 8, q is equal to 2, 4 and 8 respectively, observe their time domain and amplitude frequency characteristics, and understand the impact on the time domain and amplitude frequency characteristics of the signal sequence when Q takes different values < / P > < p > ② fixed q = 8, P is equal to 8, 13 and 14 respectively, observe the impact of P change on the time domain and amplitude frequency characteristics of the signal sequence, and pay attention to the obvious leakage phenomenon when p is equal to, Does aliasing also occur < p > record the phenomena observed in the experiment, and draw the corresponding time-domain sequence and amplitude frequency characteristic curve
