Scaling equation.


roposition

(Scaling equation) Let MATH be an MRA. There exists a sequence MATH such that MATH Furthermore MATH

Proof

The equation $\left( \#\right) $ follows from the proposition ( Subspace bases ) and the definition ( Multiresolution analysis )-1 for $d=0$ . The inclusion MATH follows from the proposition ( Parseval equality ).

We take Fourier transform of $\left( \#\right) $ : MATH and use the formula ( Property of scale and transport 6 ): MATH MATH

Definition

(Scaling filter and auxiliary function) In context of the proposition ( Scaling equation ), the sequence MATH is called "scaling filter" and the function $m_{0}$ is called "auxiliary function".
