IQmodulation
Quadrature amplitude modulation (QAM) is both an analog and a digital modulation scheme. It conveys two analog message signals, or two digital bit streams, by changing (modulating) the amplitudes of two carrier waves, using the amplitude-shift keying (ASK) digital modulation scheme or amplitude modulation (AM) analog modulation scheme.

说明: 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(Observed Gaussian sequence in time domain and amplitude-frequency characteristics. ① fixed p = 8, q is equal to 2,4,8 respectively, to observe them in time domain and amplitude-frequency characteristics, to understand when the different values of q, the signal sequence in time domain and amplitude-frequency characteristics of ② fixed q = 8 , p is equal to 8,13,14 respectively, to observe the changes in the signal sequence p in time domain and amplitude-frequency characteristics, note that p is equal to the number when the apparent leakage phenomenon, aliasing is also gone? Records of the experiment was observed phenomenon, draw the corresponding time-domain sequence and amplitude-frequency characteristic curves)
