Patent ID: 8166333

Claim:
A network signal processing apparatus comprising: a first signal processing module operated in an asynchronous domain, wherein the first signal processing module is utilized for processing a network signal to output a first processed signal; a first sampling rate converter coupled to the first signal processing module, wherein the first sampling rate converter is utilized for performing signal frequency conversion on the first processed signal according to a first timing adjustment signal and outputting a first converted signal; a second signal processing module operated in a synchronous domain and coupled to the first sampling rate converter, wherein the second signal processing module is utilized for processing the first converted signal to output a second processed signal; a second sampling rate converter, coupled between the first signal processing module and the second signal processing module, for performing signal frequency conversion on the second processed signal according to a second timing adjustment signal and outputting a second converted signal to the first signal processing module; and a timing controller, coupled to the first and the second sampling rate converters, for generating the first timing adjustment signal to the first sampling rate converter and generating the second timing adjustment signal to the second sampling rate converter so as to adjust the timing of both the first and the second converted signal, wherein the timing controller outputs the first and the second timing adjustment signals according to the second processed signal.
