说明：  滤波器采样频率为600Hz ，截止频率100Hz 的10阶低通滤波器。并用汇编语言设计一个实现上面要求的FIR 滤波器 (2)要求设计滤波器采样频率为8000Hz ，截止频率500Hz 的40阶低通滤波器。用C语言设计一个实现上面要求的FIR 滤波器
(Filter sampling frequency of 600Hz, the 10 cut-off frequency 100Hz-order low-pass filter. Design and assembly language to achieve the above requirements of a FIR filter (2) require the design of filter for sampling frequency 8000Hz, the 40 cut-off frequency 500Hz-order low-pass filter. Design using C language to achieve the above requirements of a FIR filter)
