PID仿真程序，只需要人工修改PID参数，及根据自身情况修改模型参数就可以轻松实现PID仿真。(PID code in matlab)

AM、DSB 调制及解调 用matlab产生一个频率为1Hz，功率为1的余弦信源m(t)，设载波频率ωc =10 Hz， m0 = 2 ,试画出： 􀁺 AM 及DSB 调制信号的时域波形； 􀁺 采用相干解调后的 AM 及DSB 信号波形； 􀁺 AM 及DSB 已调信号的功率谱； 􀁺 调整载波频率及 m0，观察分的AM 的过调与DSB 反相点现象。 􀁺 在接收端带通后加上窄带高斯噪声，单边功率谱密度0 n = 0.1，重新解调。 (AM, DSB modulation and demodulation Matlab produce a frequency for 1 Hz, power of 1 cosine source m (t), set the carrier frequency ω c = 10 Hz, M0 = 2, try drawing out: )
