摘要 在超声诊断系统中,一个重要的环节就是实时处理庞大的超声信号,尤其是用数字硬件电路实时进行信号处理.信号处理的关键部分就是滤波器的设计,数字滤波器的设计会直接影响超声诊断设备的性能.简要介绍数字滤波器的分类,着重介绍近年来基于现场可编程门阵列(FPGA)的多种数字滤波器的硬件实现方法,尤其是经典数字滤波器中基于分布式算法实现有限脉冲响应(FIR)滤波器;分析了每种数字滤波器的优点及存在的问题;展望了超声诊断设备中现代数字滤波器的发展趋势. A large real-time processing of ultrasonic signals is a very important part in the ultrasound diagnosis system,especially with digital hardware processing.A key part of the signal processing is the filter design which will affect the performance of ultrasound diagnostic equipment.In this paper,the classification of digital filters is introduced briefly,and a number of hardware implementation methods of digital filter in recent years,especially the realization of FIR filters which belongs to the classical filter based on Distributed Algorithms are discussed.Then a number of advantages and problems of digital filter in recent years are analyzed.On this basis,the paper forecasts its developing trends in the future.
