【摘要】 数字滤波器是一种广泛采用的信号处理部件,其基本的两类FIR和IIR各有特点,而用FPGA实现可使其实时性得到满足,得到了人们的认可。本文介绍了一种在Simulink仿真后,再借助DSPBuilder将其转换可单独使用的模块的方法,该方法可使人们更方便地使用FPGA,最后还通过仿真试验证明了两类滤波器的优劣。更多还原

【Abstract】 The digital filter is a kind of signal processing unit used abroad. The finite impulse response filter and the infinite impulse response filter are basic digital filters, they have their own character. If we realized the filters in FPGA, the real time nature can be satisfied, so people recognize the method. The paper aimed at a plan that we can first simulate in Simulink, and then transform a new module with DSPBuilder. The plan can make the using of FPGA more simply. In the end of the paper, a simulate experiment is adopted to testify the ferior and inferior of the two fihers.更多还原
