基于开关电流电路的小波变换实现

摘要

本文提出了用开关电流实现连续小波变换的一种方案,用Legendre基数代替经典Padé逼近中的函数序列｛xi:i=1,2,3…}来逼近小波函数,并利用开关电流电路实现该小波函数滤波器,理论分析和仿真结果证实了该方案的可行性.%An implementation of wavelet transform based on switched-current circuit is proposed. The transfer functions of the wavelet can be given by Pade approximation of which the classic function order {x1: I=1,2,3…} is replaced by Legendrepolynomial, and implement these wavelet function filters with switched-current circuits. Theoretical analysis and simulation results indicate a good performance of wavelet transform.
