A processing apparatus for calibrating an analog filter of a communication device in a digital domain is disclosed, wherein the analog filter is arranged to perform a filtering operation upon a communication signal in an analog domain. The processing apparatus includes a signal processing circuit and a digital filter. The signal processing circuit is used for transforming the communication signal between the digital domain and the analog domain. The digital filter is coupled to the signal processing circuit, and used for performing a filtering operation upon the communication signal in the digital domain, wherein a frequency response of the digital filter is arranged to compensate a frequency response of the analog filter according to at least a compensation parameter generated with reference to a frequency-related characteristic of the analog filter.
