Why does the variance not coincide with the autocorrelation function in 0?
var(x) = sum((x-mean(x)).^2)/1000 while y(lags==0) is just calculating sum(x.^2). Because of the normalization var does your res...

Compute the Fourier Transform for: x(n)=u(n)-u(n-6); x(n)=[(2^n)*u]*(-n); x(n)=[-2,-1,0,1,2]
Hello, I believe you are trying to calculate the Fourier Transform of the three signals. x[n] = u[n]-u[n-6] = 1, n = 0,1,...5,...
