摘　　要：针对超声波无损检测中检测信号存在噪声干扰这一问题,采用了将乘加运算转化为查找表的并行分布式算法,在FPGA上实现了一个16阶FIR低通滤波器。通过QuartusII进行硬件仿真,仿真结果表明设计的FIR滤波器滤波效果良好,且运行速度较快。The focus of this paper is to decrease the noise that inpacting the ultrasonic nondestructive testing signals. Using a parallel distributed algorithm which can transfer multiply-add operations into the lookup table to design a 16-step parallel fir filter based on FPGA .The filter was simulated by Quatus II., the hardware simulation result shows that the designed FIR filter is good and run faster.
