摘要：

A new approach to numerical wavelet transforms is described where sampled n-dimensional signal data are treated as finite functions on discrete tori T-n. This approach shows that the undecimated numerical wavelet transform leads to decomposition onto a frame in the space of square-summable functions on the discrete torus l(2) (T-n).
