2results about How to "Improve filtering efficiency" patented technology

The application discloses a filter and a synchronization signal processing method. The filter comprises a first filter set and a second filter set; input ends of the first filter set and the second filter set are connected to a signal sampling component; output ends of the first filter set and the second filter set are connected to a filter output end; the signal sampling component is used for collecting a double-sampling-point communication signal and transmitting the communication signal to the first filter set and the second filter set; the first filter set is used for receiving a first communication signal and filtering the first communication signal to obtain a first filtered signal; the second filter set is used for receiving a second communication signal and filtering the second communication signal to obtain a second filtered signal; and the filter output end is used for coupling the first filtered signal and the second filtered signal to obtain a final filtered signal. According to the embodiment of the application, the downsampling is realized while the filtering precision is ensured, and the operation amount is reduced.

The utility model provides a swing type screening device of plastic recycling, including the blanking base, the bottom rotation of blanking base is connected with the rotating base, and the rotating base bottom is equipped with the discharge gate, the eccentric position of rotating base bottom is arranged to the discharge gate, the below of blanking base is equipped with the filter screen frame, is equipped with the filter screen mesh plate on the filter screen frame, the top of filter screen frame is equipped with the material shifting guide plate. The utility model discloses through the work of control motor support, makes the output shaft on motor support so is equipped with the drive gear and the external gear that the rotating base upper end sets is engaged transmission, drives the rotating base to rotate, thereby the rotating change position of the discharge gate that rotating base bottom sets, in the process that material is along the discharge gate guide and falls, makes the falling track of material to rotate swing, thereby effectively even the material is scattered on the filter screen mesh plate top, improves the screening efficiency of filter screen mesh plate.
