A Wavelet
processor in real time mode is presented in this article. Prior an
ideal macromodel simulates this processor. The two principal
problems associated, the generation of the wavelet function
waveform and the generation of the Timescale resolution grid,
were solved in this article. A general procedure
to obtain the wavelet or scaling function waveform from a set of
quadrature mirror coefficient filters (QMF's) is the starting point
of this article. As an example, a Daubechies 3, Db3 or D6 Wavelet
waveform generator was designed and constructed. For the generation
of the time-scale resolution grid a new analog network was
developed. This network, a switched capacitor network, makes an
expansion in time of the mother wavelet function and reproduces it
in a parallel dyadic structure.
