# Autocorelation and binary sequence ?? watch

1. Hi I have been given a sequence that contains 16 digits consisting of +1 and -1. I am asked to calculate all of its autocorelation values.

In the book i am studying, it has very little information that explains how to handle this but i couldn't quite understand where its trying to take me... So here what the book says:

"Take n = 7 and put g = (0100111). Determine all the autocorrelation values. Write several copiesof ~g one after each other, and count how many runs of the various lengths of the two bits there are. "

Can anybody enlighten me given that the question that has 16 digits also asks to make a diagram. So my solution will have to include diagram?
