The DWT coefficient ${c}_{m,n}$ is given by

${c}_{m,n}={\int}_{-\infty}^{+\infty}{{x(t)\mathrm{\Psi}}^{*}}_{m,n}(t)dt$ (43)

Here wavelets are orthonormal functions obtained by shifting and dilating a mother wavelet $\psi (t)$

${\mathrm{\Psi}}_{m,n}(t)={2}^{-m/2}\mathrm{\Psi}({2}^{-m}t-n)$ (44)

(44)

As $m$ increases, the wavelets stretch ...
