A VLSI implementation of the continuous wavelet transform
R. Timothy Edwards, C. Cauwenberghs · 1996
We have designed and fabricated a VLSI circuit which performs a continuous wavelet transform on a one-dimensional (e.g., sound) input in real time. This implementation uses oversampling techniques and simple switched capacitor filters to achieve good signal quality in a system which is small and consumes little power. Measurement results that validate correct operation of wavelet decomposition are included.
