WebW (n) = Hamming window First Question: I have "framed" (split the signal into blocks), so therefore, in X (n) do I pass in the values for each block, and, not the block itself? Second question regarding the Hamming Window: The equation is given: From this I get: w (n) = new vector e.g. w (0) = 0.54 - 0.46 cos () This is where I get lost.
