<p>A network device (10) includes a communication slot (100), a first signal processing circuit (300), a second signal processing circuit (400), and a central processing unit (200). The communication slot is used for receiving signals of different bands. The first signal processing circuit is connected to the communication slot, and is used for selecting a first band signal from the signals of different bands, and processing the first band signal thereby generating a processed first band signal. The second signal processing circuit is connected to the communication slot, and is used for selecting a second band signal from the signals of different bands, and processing the second band signal thereby generating a processed second band signal. The central processing unit is connected to the first and the second signal processing circuits, and is used for processing the processed first and second band signals.</p> |
