(i) U(n) corresponds to short-time energy or amplitude if T in eq. is squaring or absolute magnitude.

$ E_n(n) = \sum_{m-w}^w [S(m)W(n-m)]^2 \\ E_n(n) = S^2(m) \times h(m) \\ M(n) = |S(m)| \times W(m) $

(ii) Squaring of the signal to calculate energy would emphasize high amplitude.

(iii) Magnitude measurements …
