This chapter describes the next step towards the implementation of wavelet filters. Departing from the transfer functions defined in Chapter 4, we derive a state space description of the wavelet filter. Since state space descriptions are not unique representations of a dynamical system, they allow the designer to find an implementation that fits best to the requirements imposed, e.g. coefficients that are readily implemented, a prescribed circuit topology, or maximum dynamic range. The description is transformed into the desired form by state space transforms or similarity transforms. In the context of low-power, low-voltage analogue integrated circuits, the most important requirements are dynamic range, sensitivity, and sparsity, all of which are treated in Chapter 5.
