    Guy,

    I am studying Digital Signal Processing (DSP) , i come across one problem in Power Signal equation, you see i cannot understand why the power equation
    is N + 1 / 2N + 1 ( how the N + 1, come from ) ...see my attachment will be more clear for you...Thanks..

    If you add a bunch of 1's together then you get a sum that is equal to the number of 1's. So if the index runs from 0 to N, how many 1's is that? Well it is the difference in the indices plus 1
    Code ( (Unknown Language)):
    1.  
    2. (N - 0) + 1 = N + 1
    3.
