适合于实现小波变换的多回路反馈对数域带通滤波器
the multi-loop feedback bandpass filter for the implementation of wavelet transfer
连续小波变换(CWT)是一个非常有用的信号处理技术，它的母小波函数可以用带通滤波器来实现。本文描述了一个可以用来作为实现小波变换的基本模块的对数域带通滤波器，此带通滤波器使用了多回路反馈的结构。通过用PSPICE仿真，仿真结果表明这个对数域带通滤波器适合于低电压低功耗和高频应用。
ontinuous Wavelet Transform (CWT) is a highly useful processing technique. It is based around a mother wavelet function which acts as a bandpass filter. This paper describes a log-domain bandpass filter as a basic building block of the CWT using multiple loop feedback structures. Simulation results are also given by using PSPICE. The proposed circuits are suitable for low-voltage low-power operation and high-frequency application.
