    hi everyone,
    I need help in a project.I have a signal x(n)=(0.5^n)*u(n). i want to find the DFT of the signal for N1=50,N2=20,N3=11 and then the reconstruction of the signal. I don't know anything about matlab and i don't have any idea how i'll do this. My problem is the code so if someone can help me please do. thanks!!!
