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 Time—scale 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.
