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.)
选择三个不同频段的信号对其进行频谱分析,根据信号的频谱特征设计三个不同的数字滤波器,将三路信号合成一路信号,分析合成信号的时域和频域特点,然后将合成信号分别通过设计好的三个数字滤波器,分离出原来的三路信号,分析得到的三路信号的时域波形和频谱,与原始信号进行比较,说明频分复用的特点。(Choice of three different signal-band spectral analysis carried out, according to the characteristics of the design spectrum signals of three different digital filter, the signal will be three-way all the way signal synthesis, analysis of time-domain signal synthesis and frequency domain characteristics of signals and then synthetic through three digital filter designed to isolate the original three-way signal, the three-way analysis of time-domain signal waveform and spectrum, compared with the original signal on frequency division multiplexing features.)
