摘要
在数字信号处理中,数字滤波占有极其重要的地位。数字滤波是语音和图象处理、模式识别、谱分析等应用中的一个基本处理算法。在许多信号处理应用中用数字滤波器替代模拟滤波器具有许多优势。用DSP芯片实现数字滤波除了具有稳定性好、精确度高、不受环境影响外,还具有灵活性好的特点。该文对数字滤波器的设计与实现方法进行了研究。
In digital signal processing,digital filtering an extremely important position.Digital filtering are voice and image processing,pat-tern recognition,spectral analysis applications such as a basic treatment algorithm.In many signal processing applications using the digital fil-ter alternative filter has many advantages Analog.Implementation using DSP chip digital filtering except with good stability,high accuracy,free from environmental impact,but also the characteristics of good flexibility.In this paper,digital filter design and implementation meth-ods were studied.
