    I would like to know how to approach this question, looks easy but I just don't know where to start, thanks.



    1. Define orthogonality for both continuous and discrete time signal giving the formula in both cases:
    s1[n]=1,0,0,1,1,1,0,1
    s2[n]=1,1,0,0,1,1,0,0


    x(t)= sin(2∏t) y(t)=cos (2∏t) are they orthogonal over t=-1 and t=1 sec ?




    I know that:

    Formula for continuous signal is: Formula for discrete signal is:
    T N-1
    ∫ x(t).y(t)dt=0 (1/N) Ʃ x[n].y[n]=0
    0 n=0

    and then:confused:?
