Summary:在音频信号处理领域滤波器往往是关键的部件。而随着娱乐媒体的发展,高精度的音频信号被广泛使用,多通道更是音频信号处理的重要需求之一。基于这一强烈应用需求驱动,设计了一款基于FPGA并满足可扩展的多通道IIR滤波器。通过分析仿真测试输出数据的频谱,验证该硬件滤波器的性能满足设计要求。
Bibliography:Filter is one of the most important components adopted in audio signal process system. Specifically, along with the de- velopment of the multimedia and entertainment technology, high-precision audio signals are widely used, and multi-channel is one of significant requirements for audio signal process. Driven by this strong application requirement, a scalable muhi-channel IIR digital filter is proposed. By analyzing the frequency spectrum, this filter is proven to satisfy the design requirements.
