小学期的源程序 1．试编MATLAB程序。信号 sinc(10*t),-2<=t<=2 m(t)= 0,其它 用100hz的载波来产DSB信号并解调。完成下列工作： 画出已调信号； 求已调信号的频谱，并用图像表示。 画出解调信号； 求解调信号的频谱，并用图像表示。 2．信号 sinc2(100t),|t|≤t0 m(t)= 0, 其它 采用频率调制调制为1000HZ的载波。频偏常数为kf=50,t0=0.2

Descr iption A group of N people wishes to go across a river with only one boat, which can at most carry two persons. Therefore some sort of shuttle arrangement must be arranged in order to row the boat back and forth so that all people may cros
