Problem 6: Matlab Code: dt=0.1; %time step t1=0:dt:2; t2=0:dt:4; x1=ones(1,length(t1)); x2=ones(1,length(t2)); y=conv(x1,x2); %Note that convolution length: t is the sum of the lengths of t1 and t2 t=0:dt:6; %scale y with time step dt y=y*dt; %Note:you don’t need to use these functions, I just wanted to introduce you %to some new plot properties subplot(1,2,1),plot(t1,x1);title('x1 vs time'),xlabel('t'),ylabel('x1') subplot(1,2,2),plot(t2,x2);title('x2 vs time'),xlabel('t'),ylabel('x2') figure,plot(t,y); Figure 1, Plot and x1 and x2 wrt time

Unformatted text preview: Figure 2 , Plot of resulting convolution y wrt time NOTE: This part is not included to homework; I just put these for you so that you can see how the created arrays look like in Matlab. When you convolve x1 and x2(by taking the integral of x1 and x2) what you do is multiplying corresponding x1 and x2 values and the time interval, and then summing up these values. Since Matlab do not multiply the values with the time interval while convolving functions, you need to scale the result by multiplying dt after the convolution....

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
