An Implementation of an Orthogonal Continuous Wavelet Transform by Using Log-domain Circuits

摘要

This paper proposed an implementation of an orthogonal decomposition of temporal signals by using a Laguerre structure and log-domain circuits, which has a characteristic of high-speed, expanded frequency, simplified and low-voltage low-power. The PSPICE and Matlab simulation of the multi-resolution processor and the basic cell such as AP and LPF are given. The results show that the orthogonal wavelet transform companding circuit proposed in the article is feasible.
