Abstract :
We have developed the theory and analog hardware implementation for a Continuous Wavelet Transform (CWT). This novel circuit performs an orthogonal decomposition of temporal signals, such as speech, in a frequency range of 10 Hz to 20 kHz. This multiresolution processor expands the Laguerre structure originally developed by Lee (1960)
