Hi, I'm sorry if I post this thread at the wrong section. I have a question regarding sequences.
Qn: if there is a sequence x(n) = (0.5)^n u(n), find the energies of the latter sequence of x(2n) and x(0.5n). Also, how the even and odd sequence of x(2n) and x(0.5n) relate to those of x(n)
first, I'm not sure what does it mean by "find the energies of the latter sequence of..." and second, i don't know how to relate those sequences to those of x(n). Is there anyone who can help me? Any help will be greatly appreciated.
Thanks!
