陷波器是一种特殊的带阻滤波器,其阻带在理想情况下只有一个频率点,因此也被称为点阻滤波器。这种滤波器主要用于消除某个特定频率的干扰,例如,在各种测量仪器和数据采集系统中用于消除电源干扰的工频陷波器。该程序实现利用陷波滤波器消除图像的电源干扰。(Notch is a special band rejection filter, the stop band in the ideal case , only one frequency , it is also known as point-stop filter . This filter is mainly used to eliminate the interference of a particular frequency , for example , in a variety of measuring instruments and data acquisition system is used to eliminate the power line frequency interference notch filter . The program implements the use of a notch filter to eliminate power disturbances image.)
