| description | The invention discloses a fast correction method for multi-channel frequency domain compensation. A standard sinusoidal signal is generated under manual frequency control; one marker register is set for each frequency sampling point; sweep-frequency sampling is carried out on one channel by a sweeping-frequency method; a filter is disconnected by means of manual filter switching; FFT amplitude measurement is carried out on a sampling signal by invoking an MATLAB tool and thus a frequency response curve and a filter coefficient are generated; and then the filter coefficient is updated and the sampling signal is filtered by the filter to complete channel correction. The above-mentioned steps are repeated to complete quick multi-channel correction.
本发明公开了种多通道频域补偿的快速校正方法，先通过手动频率控制下产生标准正弦信号，再对每个频率采样点设置个标志寄存器，通过扫频法对其中个通道进行扫频采样，再通过手动滤波切换方式，断开滤波器，调用MATLAB工具对采样信号进行FFT测幅，进而生成频响曲线和滤波器系数，最后更新滤波器系数，并通过滤波器对采样信号进行滤波，完成该通道的校正，然后依次类推，完成多通道的快速校正。 |
