Reading data†

Derivation†

• Mathematical formula

  &texvc("\frac{\partial y}{\partial t}(t) \approx \frac{y[n+1]-y[n]}{(n+1)-n} = y[n+1]-y[n]");

Autocorrelation†

• Mathematical fomula

  &texvc("R_{y}[L] = \sum^{N}_{n=0}y[n] \times y[n-L]");

Find interval†

Extraction†

Discrimination†

Store results†
