说明: 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。
注:(求和代替积分)
3.信号
2, t0/3>t>0
m(t)= -6, t0/3<=t<2*t0/3
0, 其它
t0=0.15,使用AM调制和包络检波解调.
(Primary phase of source 1. Test procedures for MATLAB. Signal sinc (10* t),-2 < = t < = 2 m (t) = 0, the other with the 100hz signal carrier to the middle class and DSB demodulation. To complete the following tasks: Draw has been transferred signal for the spectrum signals have been adjusted, and image representation. Draw demodulation signal solving transfer spectrum signal, and image representation. 2. Signal sinc2 (100t), | t | ≤ t0 m (t) = 0, the other the use of frequency modulation of the carrier modulation for 1000HZ. Offset constant kf = 50, t0 = 0.2. Note: (sum in lieu of points) 3. Signal 2, t0/3> t> 0 m (t) =-6, t0/3 < = t < 2* t0/3 0, other t0 = 0.15, the use of AM modulation and demodulation envelope detector.)
