x1=0.2*(sin(2*pi*150*t)) = 0.05<=t<=0.1

x2=0.4*(sin(2*pi*50*t)) = 0.15<=t<=0.25

x3=(sin(2*pi*10*t)) = 0<=t<=0.3

x=x1+x2+x3;

How to write equation in matlab so that i can get the following plots?

t = 0:0.001:0.3;

x1 = 0.2*sin(2*pi*150*t); x1(t<=0.05 | t>=0.1) = 0;

x2 = 0.4*sin(2*pi*50*t); x2(t<=0.15 | t>=0.25) = 0;

x3 = sin(2*pi*10*t);

x = x1+x2+x3;

subplot(2,2,1)

plot(t,x1)

subplot(2,2,2)

plot(t,x2)

subplot(2,2,3)

plot(t,x3)

subplot(2,2,4)

plot(t,x)
