Analog optical colorimeter is used to calibrate correcting filter so as to make it meet Luther condition. However, the calibration precision of the filter is influenced by many factors.
光学模拟测色仪采用校正滤色器使仪器满足卢瑟条件，校正滤色器的精度受多种因素的影响。
Then a linear programming method is proposed to construct the FIR filter correcting the amplitude and phase errors simultaneously.
然后给出了求解逼近给定幅相频率响应的FIR实系数滤波器的线性规划方法；
