This is the communication in the digital wave of context, the application of computer technology and the development of information technology results. Digital signal filter in a variety of digital signal processing plays an important role, digital signal design digital signal processing has been an important research topic in the field. In recent years, Digital Signal Technology in China has been developing rapidly, both in scientific and technological research and development is failing in its application more and more widely, and achieved fruitful results.Therefore, this artcle introduced the FIR filter may realize the strict linear phase under the window function and Remez function, designs gronp of filters coefficients ,vses least squares method to optimize these coefficients .in the foundation which smallest...
