编写程序验证序列傅里叶变换频移性质，时域卷积定理〔时域卷积后的频域特性〕。〔所需信号自行选择〕
4. 时域差分方程的求解
(n)＋a1y(n-1)＋a2y(n-2)=b0x(n)＋b1x(n-1)的零状态响应和全响应。已知X(n)为单位取样序列，y(-1)=1,y(-2)=2,a1=,a2=,b0=2,b1＝3。
5. 离散系统的Z域分析
利用系统函数分析系统的稳定性。假设系统函数如下式：
，试判断系统是否稳定。
已知线性时不变系统的系统函数，编写程序求其单位取样响应，频率响应及系统零极点，并画出相应图形。
6. 创新训练拓展内容
利用Matlab自带的录音功能，或利用Goldwave等音频编辑软件，对语音或其他音频信号进行采集并保存为*.wav文件。
要求：〔1〕采用不同的采样频率〔2000Hz，4000Hz，8000Hz，16000Hz等〕。
〔2〕对采集得到的信号进行播放。
〔3〕分析在不同采样频率下得到的信号有何不同。
设定一个连续时间信号，进行抽样和恢复，要求分析不同采样频率对恢复结果的
