u(t)=sinc⁡(100t)and y(t)=cos(400πt) and x(t)=u(t)*y(t)

u(t)=sinc⁡(100t)and y(t)=cos(400πt) and x(t)=u(t)*y(t)

Now I need the code for plotting u(t) , |U(F)|, y(t), |Y(F)| , x(t) and |X(F)|

This sounds like a homework assignment. If it is, show us the code you've written to try to solve the problem and ask a specific question about where you're having difficulty and we may be able to provide some guidance.

If you aren't sure where to start because you're not familiar with how to write MATLAB code, I suggest you start with the free MATLAB Onramp tutorial to quickly learn the essentials of MATLAB.

If you aren't sure where to start because you're not familiar with the mathematics you'll need to solve the problem, I recommend asking your professor and/or teaching assistant for help.

I have written the code like this but not sure is it okay or not

t=linspace(-10,10)

u=sinc(100*t)

subplot(6,1,1)

plot(t,u)

U=fft(u)

Uabs=abs(U)

subplot(6,1,2)

plot(t,fftshift(Uabs))

c=cos(400*pi*t)

subplot(6,1,3)

plot(t,c)

C=fft(c)

Cabs=abs(C)

subplot(6,1,4)

plot(t,fftshift(Cabs))

x=u.*c

subplot(6,1,5)

plot(t,x)

X=fft(x)

Xabs=abs(X)

subplot(6,1,6)

plot(t,fftshift(Xabs))

We do not know. U(F) and similar are not defined in the posted question

Answer 1

[Walter Roberson]

syms t
u(t) = sinc(17*t)

u(t) = 

fplot(u)

[Mashrur Zawad]

It doesn't answer whole question

[Walter Roberson]

It shows you how to construct functions, and it shows you how to plot functions. The only thing missing is the information that in MATLAB, π can be coded for symbolic use as

Pi = sym(pi);

and then refer to Pi .

Beyond that, there can be one or two additional steps depending whether each plot is to be in its own figure, or each plot is to be in its own axes (and if so should the 6 plots be 6 vertical, 6 horizontal, 3 vertical and 2 horizontal?) or if all of the plots should be on the same axes.

We are not here to answer people's homework questions: we are here to teach people how to use MATLAB.
