show
that H(w) is a periodic function in w, and without any other
assumption, please tell me what the period is. Then, explain that
if we
are given H(w), how to recover x(n). (Notice that we defined
H(w)
above by a linear mapping of x(n), so this means to find the
inverse
linear mapping of H(w) that will give you x(n).)...
