[DSP program] FIR123 DL : 0: 1.利用Matlab进行产生频率为1000Hz和6000Hz的正弦信号，利用FDATOOL设计FIR滤波器(fs=16000Hz)，以滤波6000Hz分量，并利用SPTOOL工具对信号滤波进行仿真与验证。 2.从MIC端口(J5)输入频率为1000Hz和6000Hz正弦信号的叠加信号，编写实时FIR滤波程序，选择合适的滤波器参数，滤除6000Hz的频率分量，利用示波器在SPEAKER端口(J6)观察输出波形。分析信号的频谱结构，设计满足要求的数字滤波器,-1. The use of Matlab have 1000Hz frequency of 6000Hz, and the sinusoidal signal, use FDATOOL design FIR filter (fs = 16000Hz) 6000Hz to filter components, and use SPTOOL right signal filtering tools for simulation and verification. 2. MIC from the port (J5) input frequency of 1000Hz and 6000Hz sinusoidal signal superimposed signal Real-time preparation of FIR filtering process to select an appropriate filter parameters, filter 6000Hz frequency components, SPEAKER oscilloscope using the port (J6) to observe the output waveform. Spectrum Signal Analysis of the structure and design meet the requirements of the digital filter.
