1. Normalization 1.1. Purpose Normalize a signal by subtracting its mean and dividing by its standard deviation. 1.2. Description A signal \(x=x(k)\) is normalized by subtracting its mean \(\bar{x}\) and dividing by its standard deviation \(\sigma_x\), that is, \[x_\mathrm{norm}(k)=\frac{x(k)-\bar{x}}{\sigma_x}.\] 1.3. Input slots Any equidistant signal (see Signal Types ). 1.4. Output slots One output slot with normalized signals.
