Abstract
The utility model discloses a modularized filter. A low-pass filter circuit and a band-pass filter circuit which consists of a high-pass filter circuit and another low-pass filter circuit are arranged on a circuit board respectively. The low-pass filter circuit is connected with the high-pass filter circuit. An input end and output ends respectively corresponding to the two low-pass filter circuits are arranged on the circuit board. A shift switch is arranged on the position of the input end, and the position is corresponding to the joint between the low-pass filter circuit and the high-pass filter circuit, meanwhile another shift switch is arranged between the high-pass filter circuit and the other low-pass filter circuit. Therefore, the modularized filter can be arranged on a multimedia wide frequency sharing device to be respectively connected with the multimedia wide frequency sharing device and televisions or other circuits inside the multimedia wide frequency sharing device, so that the multimedia wide frequency sharing device can be directly shifted and controlled by the shift switch. The filter can be connected with the televisions or various digital multimedia devices without being connected with other shift switches or replacing different filters. The utility value is increased during the using process of the entire filter.
