SIGNAL PROCESSING CIRCUIT

WIPO Patent Application WO/2016/086384

A1

Disclosed in the present invention is a signal processing circuit, comprising: an AD/VD digital front end, a G.fast digital front end, a first switching circuit, a second switching circuit, a first drive circuit, a first hybrid circuit and a first transformer. The AD/VD digital front end and the G.fast digital front end are respectively connected to one end of the first switching circuit and one end of the second switching circuit, and the other end of the first switching circuit is connected to one end of the first drive circuit, and the other end of the first drive circuit is connected to one end of the first hybrid circuit, and the other end of the second switching circuit is connected to the other end of the first hybrid circuit, and the other end of the first hybrid circuit is connected to one end of the first transformer. The circuit can make two different service models of G.fast and VDSL2 to coexist in the same cable, and can use high-frequency and low-frequency to jointly carry the service, improving service efficiency. The circuit has a simple structure and the device is small in quantity and size, and is convenient to arrange.
