1、学生实验报告实验名称：连续时间信号的描述及运算学生姓名：班级：08电科一学号：指导老师：赵丽莉同组人：成绩：实验目的:熟悉掌握利用Matlab产生基本连续时间信号及信号的时域运算实验要求：编制Matlab程序，实现以下内容1利用信号处理工具箱提供函数生成单位冲激函数、单位阶跃函数、单边指数函数()。2设信号，用Matlab求，，，，，并绘出其时域波形。实验方法（步骤）：实验程序；1单位冲激函数t0=0;tf=5;dt=0.01;t1=1;t=[t0:dt:tf];st=length(t);n1=floor((t1-t0)/dt);%求t1对应的样本序号x

2、1=zeros(1,st);%把全部信号先初始化为零x1(n1)=1/dt;%给出t1处的脉冲信号stairs(t,x1)%绘图axis([0,5,0,22])批阅老师：年月日第12页共3页学生实验报告单位阶跃functionf=heaviside(t)t=-1:0.01:3f=heaviside(t)%heaviside单位阶跃函数plot(t,f)axis([-1,3,-0.2,1.2])t=Columns1through6-1.0000-0.9900-0.9800-0.9700-0.9600-0.9500Columns7through12-0.94
