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

I am trying to representate a SPWM comparing a 30kHz triangle wave with a 60Hz sine wave using the MatLAB. However, I do not know how to compare two functions in him. Recently I generated this graph containg the sine and the triangle wave functions..
