If you already have produced an input signal xin, before using it, you must remove its dc component:

Much depends on what you intend by ‘normalize’.

If you have R2018a or later, use the normalize (link) function. This produces a z-score of your data, the equivalent of (for a vector ‘x’):

zscr = @(x) (x(:) - mean(x(:))) / std(x(:));
