摘要
基于对3类特殊小波的分析,从时域和频域两个方面,分别提出了用于实现这三类连续小波变换的新型电路结构.以3类小波的相似结构为基础,采用新型的对数域集成电路设计方法,设计实现了具有共享结构的连续小波变换系统,并进行了电路仿真实验.该系统可以同时实现3类特殊的连续小波变换,且由于对数域设计技术的引入,电路工作在电流模式状态下,具有低电压、低功耗以及灵活的宽频段可调性等特点.
Based on the analysis of three special wavelets, we constructed new circuits to implement the special continuous wavelet transform （CWT） both in time domain and frequency domain. We realized the system of CWT with the share constructs by using the new design method of log-domain circuits, and tested the circuits with PSPICE. This system could realize three special CWT, and the system, which worked as current mode circuits due to the use of the log-domain circuits technology, has characters such as low voltage, low power dissipation and flexible adjustability within a wide frequency range.
