A collection of Wj and Vj spaces allows the construction of MRAs. However, these constructed MRAs are the dyadic type that can support uniform ideal sampling processes. 2 WAVELET BASIS FUNCTIONS Wavelet Basis functions provide a system of coordinates in which several classes of linear operators are sparse. This system of coordinates is capable of expanding signals at different levels of resolution using coefficients in linear combinations of sets of basis functions. Temporal expansion is performed with contracted and highfrequency bases, while frequency analysis is performed with dilated and lowfrequency ones.

Multiswitching techniques can be realized through a modulation process that determines time instants at which switching element(s) change their status (ON to OFF or OFF to ON). Various approaches with different schemes of implementation have been developed and tested to carry out multiswitching techniques for improving inverter performance. Although extensive research has focused on operating and controlling inverters, there remains a scope to develop accurate mathematical models capable of representing the inverter function.

A scaling function φ(t) has to be capable of generating basis functions that span a set of closed spaces {Vm}, m ∈ Z. Moreover, the density and completeness conditions require an orthogonal complement space Wm for each space 38 Chapter 2 Wavelets and the Sampling Theorem Vm. Each orthogonal complement space Wm is spanned by another set of basis functions generated by φm(t). 115) k A collection of scaling spaces Vm(φ) and wavelet spaces WM(ψ) constitutes an MRA. 116) Density and completeness conditions of both spaces can be used to relate them with MRA as the scale j changes.
