Hi, I need to do convolution of the following series :
h[n] = a^(n+1) * u[n+1]
x[n] = exp(j*w*n) * u[n]
where u[n] is a step function, for n>=0, it is 1, for n<0, it is 0. "j" is imaginary part, "w" and "a" (alpha) are constants (assume they have such values the series converges). I have the following results, all somewhat different, I am somewhere wrong ?
