Question

用MATLAB绘制y=1+1/2sin（Ωt)和y=sin(8Ωt)相乘的曲线

最好有具体程序和截图

Answer 1

clf;
fs=100000;
N=10000;
n=10:N;t=n/fs;
A=2*pi*50;
x=1+1./(2*sin(A*t));
y=sin(8*A*t);
z=x.*y;
plot(t,x);

Answer 2

你的那个是sin(πt)吗？如果是的话那就这样写
t = -2*pi:pi / 100:2*pi;
y1 = 1 + (sin(pi .* t)) / 2;
y2 = sin(8*pi*t);
y = y1 .* y2;
plot(t,y),grid on;
axis([-2 2 -2 2]);
xlabel('时间轴');
ylabel('振幅');
