在数字电视技术中,诸如通讯、视频图像和音频信号处理等系统中都要求对信号处理要有实时性和灵活性,随着可编程逻辑器件和EDA技术的发展,FPGA在这些方面的优势都突显出来了,基于FPGA的信号处理器已广泛应用于各种信号处理领域。数字滤波器是现代数字信号处理系统的重要组成部分之一。IIR数字滤波器又是其中非常重要的一类滤波器,因其较低的阶次可以获得较高的频率选择特性而得到广泛应用。
In digital television technology, such as communication, video and audio signal processing systems require real-time signal processing and flexibility, with the development of programmable logic devices and EDA technology, FPGA advantages in these areas are As it stands, signal processors based on FPGAs have been widely used in various signal processing areas. Digital filters are one of the important components of modern digital signal processing systems. IIR digital filter is one of the most important type of filter, which is widely used because of its lower orders can get higher frequency selectivity.
